MAX1793EUE15-MAX1793EUE-33
Low-Dropout, Low IQ, 1A Linear Regulator
General Description
The MAX1793 low-dropout linear regulator (LDO) oper-
ates from +2.5V to +5.5V and delivers a guaranteed 1A
load current with a low 210mV dropout. The high-accu-
racy (±1%) output voltage is preset at an internally
trimmed voltage (see Ordering Information) or can be
adjusted from 1.25V to 5.0V with an external resistor-
divider.
An internal PMOS pass transistor allows a low 125µA
supply current, making the MAX1793 ideal for battery-
operated portable equipment. Other features include a
built-in reset output, low-power shutdown, and short-cir-
cuit and thermal overload protection. The MAX1793 is
available in a 1.5W, 16-pin power TSSOP package,
which is 30% smaller than a SOT223 package and only
1.1mm high.

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Low-Dropout, Low IQ, 1A Linear Regulator
ELECTRICAL CHARACTERISTICS (continued)
Note 1:
Dropout voltage is defined as VIN- VOUT, when VOUTis 100mV below the value of VOUTmeasured when VIN= VOUT(NOM)+
0.5V. Since the minimum input voltage is 2.5V, this specification in only meaningful when VOUT(NOM)≥2.5V. For VOUT(NOM)
between 2.5V and 3.3V, use the following equations: Typical Dropout = 210mV + (3.3V - VOUT(NOM)x 75mV/V; Guaranteed
Maximum Dropout = 350mV + (3.3V - VOUT(NOM)x 125mV/V. For VOUT(NOM)> 3.3V: Typical Dropout = 210mV;
Guaranteed Maximum Dropout = 350mV.
Note 2:
Specifications to -40°C are guaranteed by design and not production tested.
