Adjustable or Fixed Output
Output Current of 1A
The LM1117 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%.
Low Dropout, 1.3V max at 1A Output Current
0.04% Line Regulation
0.2% Load Regulation
100% Thermal Limit Burn-in
Fast Transient Response
