GM1117S  
1A LOW DROPOUT  
PRECISION VOLTAGE REGULATOR  
Description  
Features  
The GM1117S 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.
