_______________General Description
The MAX882/MAX883/MAX884 linear regulators maxi-
mize battery life by combining ultra-low supply currents
and low dropout voltages. They feature 200mA output
current capability at up to +125°C junction temperature
and come in a 1.5W SOIC package. The 1.5W package
(compared to 0.47W for standard SOIC packages)
allows a wider operating range for the input voltage and
output current. The MAX882/MAX883/MAX884 use a P-
channel MOSFET pass transistor to maintain a low 11µA
(15µA max) supply current from no-load to the full
200mA output. Unlike earlier bipolar regulators, there are
no PNP base current losses that increase with output
current. And, in dropout, the MOSFET does not suffer
from excessive base currents that occur when PNP tran-
sistors go into saturation. Typical dropout voltages are
220mV at 5V and 200mA, or 320mV at 3.3V and 200mA.
The MAX882 features a 7µA standby mode that disables
the output but keeps the reference, low-battery compara-
tor, and biasing circuitry alive. The MAX883/MAX884 fea-
ture a shutdown (OFF) mode that turns off all circuitry,
reducing supply current to less than 1µA. All three
devices include a low-battery-detection comparator, fold-
back current limiting, reverse-current protection, and
thermal overload protection.
The output is preset at 3.3V for the MAX882/MAX884
and 5V for the MAX883. In addition, all devices employ
Dual Mode™ operation, allowing user-adjustable outputs
from 1.25V to 11V using external resistors. The input volt-
age supply range is 2.7V to 11.5V.
For low-dropout linear regulators with output currents up
to 500mA, refer to the MAX603/MAX604 data sheet.

Note 1:
Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (TJ) within the
operating temperature range, unless otherwise noted. When operating C and E grade parts up to a TJof +125°C, expect
performance similar to M grade specifications. For TJbetween +125°C and +150°C, the output voltage may drift more.
Note 2:
(VIN- VOUT) is limited to keep the product (IOUTx (VIN- VOUT)) from exceeding the package power dissipation limits. See
Figure 5. Therefore, the combination of high output current and high supply voltage is not tested. Output current at = +125°C is guaranteed by guard banding tests at TJ= +85°C and +70°C.
Note 3:
Dropout Voltage is (VIN- VOUT) when VOUTfalls to 100mV below its nominal value at VIN= (VOUT+ 2V). For example, the
MAX883 is tested by measuring the VOUTat VIN= 7V, then VINis lowered until VOUTfalls 100mV below the measured
value. The difference (VIN- VOUT) is then measured and defined as ΔVDO.
Note 4:
Since standby mode inhibits the output but keeps all biasing circuitry alive, the Standby Quiescent Current is similar to the
normal operating quiescent current.
Note 5:
Foldback Current Limit was characterized by pulse testing to remain below the maximum junction temperature (not
production tested).
Note 6:
The Reverse-Current Protection Threshold is the output/input differential voltage (VOUT- VIN) at which reverse-current
protection switchover occurs and the pass transistor is turned off. See the section Reverse Current Protectionin the
Detailed Description.
Note 7:
Noise is tested using a bandpass amplifier with two poles at 10Hz and two poles at 10kHz.

_______________Detailed Description

The MAX882/MAX883/MAX884 are micropower, low-
dropout linear regulators designed primarily for battery-
powered applications. They feature Dual-Mode™
operation, allowing a fixed output of 5V for the MAX883
and 3.3V for the MAX882/MAX884, or an adjustable output
from 1.25V to 11V. These devices supply up to 200mA
while requiring less than 15µA quiescent current. As illus-
trated in Figure 1, they consist of a 1.20V reference, error
amplifier, MOSFET driver, P-channel pass transistor, dual-
mode comparator and feedback voltage divider.
The 1.20V reference is connected to the error amplifier’s
inverting input. The error amplifier compares this refer-
ence with the selected feedback voltage and amplifies
the difference. The MOSFET driver reads the error signal
and applies the appropriate drive to the P-channel pass
transistor. If the feedback voltage is lower than the refer-
ence, the pass transistor’s gate is pulled lower, allowing
more current to pass and increasing the output voltage. If
the feedback voltage is too high, the pass transistor gate
is pulled up, allowing less current to pass to the output.
The output voltage is fed back through either an inter-
nal resistor voltage divider connected to the OUT pin,
or an external resistor network connected to the SET
pin. The dual-mode comparator examines the SET pin
voltage and selects the feedback path used. If the SET
pin is below 65mV, internal feedback is used and the
output voltage is regulated to 5V for the MAX883 or
3.3V for the MAX882/MAX884. Additional blocks
include a foldback current limiter, reverse-current pro-
tection, a thermal sensor, shutdown or standby logic,
and a low-battery-detection comparator.
Internal P-Channel Pass Transistor

The MAX882/MAX883/MAX884 feature a 200mA P-
channel MOSFET pass transistor. This provides several
advantages over similar designs using PNP pass tran-
sistors, including longer battery life.
The P-channel MOSFET requires no base drive, which
reduces quiescent current considerably. PNP based reg-
ulators waste large amounts of current in dropout when
the pass transistor saturates. They also use high base-
drive currents under large loads. The MAX882/MAX883/
MAX884 do not suffer from these problems and consume
only 11µA of quiescent current during light loads, heavy
loads, and dropout.
Output Voltage Selection

The MAX882/MAX883/MAX884 feature Dual Mode™
operation. In preset voltage mode, the MAX883’s out-
put is set to 5V and the MAX882/MAX884’s output is set
to 3.3V, using internal trimmed feedback resistors.
Select this mode by connecting SET to ground.
In preset voltage mode, impedances between SET and
ground should be less than 100kΩ. Otherwise, spurious
conditions could cause the voltage at SET to exceed
the 65mV dual-mode threshold.
______________________________________________________________Pin Description
MAX882/MAX883/MAX884
5V/3.3V or Adjustable, Low-Dropout,
Low IQ, 200mA Linear Regulators_______________________________________________________________________________________

In adjustable mode, the user selects an output voltage
in the 1.25V to 11V range by connecting two external
resistors, used as a voltage divider, to the SET pin
(Figure 2).
The output voltage is set by the following equation:
where VSET= 1.20V.
To simplify resistor selection:
Since the input bias current at SET is nominally zero,
large resistance values can be used for R1 and R2 to
minimize power consumption without losing accuracy.
Up to 1.5MΩis acceptable for R2. Since the VSETtoler-
ance is less than ±40mV, the output can be set using
fixed resistors instead of trim pots.
Standby Mode (MAX882)

The MAX882 has a standby feature that disconnects
the input from the output when STBYis brought low, but
keeps all other circuitry awake. In this mode, VOUT
drops to 0V, and the internal biasing circuitry (including
the low-battery comparator) remains on. The maximum
quiescent current during standby is 15µA. STBYis a
comparator input with the other input internally tied to
the reference voltage. Use a resistor network as shown
in Figure 3 to set a standby-mode threshold voltage for
undervoltage lockout. Connect STBYto IN for normal
operation.
OFF Mode (MAX883/MAX884)

A low-logic input on the OFFpin shuts down the
MAX883/MAX884. In this mode, the pass transistor,
control circuit, reference, and all biases are turned off,
and the supply current is reduced to less than 1µA.
LBO is undefined in OFFmode. Connect OFFto IN for
normal operation.
