DATA SHEET
PS1117
1.0A LOW DROPOUT POSITIVE VOLTAGE REGULATOR
DESCRIPTION
The PS1117 series of positive adjustable and fixed regulators are designed to provide 1A with high
efficiency. All internal circuitry is designed to operate down to 1.3V input to output differential. On-chip
trimming adjusts the reference voltage to 1%.
FEATURES
Adjustable or Fixed Output
Output Current of 1A
Low Dropout, 1.5V max at 1A Output Current
0.04% Line Regulation
0.2 % Load Regulation
100% Thermal Limit Burn-In
Fast Transient Response
Lead Free And Halogen-Free
