MAX1793 - Maxim

MAX1793 Low-Dropout / Low IQ / 1A Linear Regulator

The MAX1793 low-dropout linear regulator (LDO) operates from +2.5V to +5.5V and delivers a guaranteed 1A load current with a low 210mV dropout. The high-accuracy (±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 resistordivider. An internal PMOS pass transistor al.

Features

include a built-in reset output, low-power shutdown, and short-circuit 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. o Guaranteed 1A Output Current o Low 210mV Dropout at 1A o Up to ±1% Output Voltage Accuracy Preset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V or 5.0V Adjustable from 1.25V to 5.0V o Reset Output (4ms delay) o Low 125µA Ground Current o 0.1µA Shutdown o Low 115µVRMS Output Noise o Thermal Overload Protection o Output Current Limit o Tiny TSSOP Power Package (1.5W) 30% Smaller .
