GENERAL DESCRIPTION
The ADP3300 is a member of the ADP330x family of precision
low dropout anyCAP™ voltage regulators. The ADP3300
stands out from conventional LDOs with a novel architecture
and an enhanced process. Its patented design requires only a
0.47 µF output capacitor for stability. This device is stable with
any capacitor, regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted appli-
cations. The ADP3300 achieves exceptional accuracy of ±0.8%
at room temperature and ±1.4% overall accuracy over tempera-
ture, line and load regulations. The dropout voltage of the
ADP3300 is only 80 mV (typical) at 50 mA.
The ADP3300 operates with a wide input voltage range from
3.0 V to 12 V and delivers a load current in excess of 50 mA. It
features an error flag that signals when the device is about to
lose regulation or when the short circuit or thermal overload
protection is activated. Other features include shutdown and
optional noise reduction capabilities. The ADP330x anyCAP™
anyCAP is a registered trademark of Analog Devices Inc.
LDO family offers a wide range of output voltages and output
current levels from 50 mA to 200 mA:
ADP3301 (100 mA)
ADP3302 (100 mA, Dual Output)
ADP3303 (200 mA)

ORDERING GUIDE
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADP3300 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

THEORY OF OPERATION
The new anyCAP™ LDO ADP3300 uses a single control loop
for regulation and reference functions. The output voltage is
sensed by a resistive voltage divider consisting of R1 and R2
which is varied to provide the available output voltage option.
Feedback is taken from this network by way of a series diode
(D1) and a second resistor divider (R3 and R4) to the input of
an amplifier.
Figure 20.Functional Block Diagram
A very high gain error amplifier is used to control this loop. The
amplifier is constructed in such a way that at equilibrium it
produces a large, temperature proportional input “offset voltage”
that is repeatable and very well controlled. The temperature-
proportional offset voltage is combined with the complimentary
diode voltage to form a “virtual bandgap” voltage, implicit in
the network, although it never appears explicitly in the circuit.
Ultimately, this patented design makes it possible to control the
loop with only one amplifier. This technique also improves the
noise characteristics of the amplifier by providing more flexibil-
ity on the trade-off of noise sources that leads to a low noise design.
The R1, R2 divider is chosen in the same ratio as the bandgap
voltage to the output voltage. Although the R1, R2 resistor
divider is loaded by the diode D1 and a second divider consist-
ing of R3 and R4, the values are chosen to produce a tempera-
ture stable output. This unique arrangement specifically corrects
for the loading of the divider so that the error resulting from
base current loading in conventional circuits is avoided.
The patented amplifier controls a new and unique noninverting
driver that drives the pass transistor, Q1. The use of this special
noninverting driver enables the frequency compensation to
include the load capacitor in a pole splitting arrangement to
achieve reduced sensitivity to the value, type and ESR of the
load capacitance.
Most LDOs place strict requirements on the range of ESR
values for the output capacitor because they are difficult to
stabilize due to the uncertainty of load capacitance and resis-
tance. Moreover, the ESR value, required to keep conventional
LDOs stable, changes depending on load and temperature.
These ESR limitations make designing with LDOs more
difficult because of their unclear specifications and extreme
variations over temperature.
This is no longer true with the ADP3300 anyCAP™ LDO. It
be stable with just a small 0.47 µF capacitor on the output.
Additional advantages of the pole splitting scheme include superior
line noise rejection and very high regulator gain, which leads to
excellent line and load regulation. An impressive ±1.4% accuracy is
guaranteed over line, load and temperature.
Additional features of the circuit include current limit, thermal
shutdown and noise reduction. Compared to the standard
solutions that give warning after the output has lost regula-
tion, the ADP3300 provides improved system performance by
enabling the ERR pin to give warning before the device loses
regulation.
As the chip’s temperature rises above 165°C, the circuit
activates a soft thermal shutdown, indicated by a signal low
on the ERR pin, to reduce the current to a safe level.
To reduce the noise gain of the loop, the node of the main
divider network (a) is made available at the noise reduction (NR)
pin, which can be bypassed with a small capacitor (10 nF–100 nF).
APPLICATION INFORMATION
Capacitor Selection:anyCAP™
Output Capacitors:as with any micropower device, output
transient response is a function of the output capacitance. The
ADP3300 is stable with a wide range of capacitor values, types
and ESR (anyCAP™). A capacitor as low as 0.47 µF is all that is
needed for stability. However, larger capacitors can be used if
high output current surges are anticipated. The ADP3300 is
stable with extremely low ESR capacitors (ESR ≈ 0), such as
multilayer ceramic capacitors (MLCC) or OSCON.
Input Bypass Capacitor:an input bypass capacitor is not
required; however, for applications where the input source is
high impedance or far from the input pins, a bypass capacitor is
recommended. Connecting a 0.47 µF capacitor from the input
to ground reduces the circuit’s sensitivity to PC board layout. If
a bigger output capacitor is used, the input capacitor should be
1 µF minimum.
Noise Reduction
A noise reduction capacitor (CNR) can be used to further reduce
the noise by 6 dB–10 dB (Figure 21). Low leakage capacitors in
the 10 nF–100 nF range provide the best performance. For load
current less than 200 µA, a 4.7 µF output capacitor provides the
lowest noise and the best overall performance. Since the noise
reduction pin (NR) is internally connected to a high impedance
node, any connection to this node should be carefully done to
avoid noise pickup from external sources. The pad connected to
this pin should be as small as possible. Long PC board traces
are not recommended.5
