GM1112¹
1A LOW DROPOUT
PRECISION VOLTAGE REGULATOR
Description
The GM1112 is a positive low dropout
regulator and is available in an adjustable
version and fixed output voltage at 1.2V. 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.
