Gamma GM1117-2.85TC3T 1a low dropout precision voltage regulator Datasheet

GM1117
1A LOW DROPOUT
PRECISION VOLTAGE REGULATOR
Features
Description
The GM1117 is a positive low dropout
regulator and is available in an adjustable
version and fixed output voltage from 1.5V to
5.0V. All internal circuitry is designed to
operate down to 800mV input to output
differential and the dropout voltage is fully
specified as a function of load current. On chip
trimming adjusts the reference/output voltage
to within ± 1%. Current limit is also trimmed in
order to minimize the stress on both the
regulator and the power source circuitry under
overloaded conditions.
