CYStek Product Specification
1A Low Dropout Positive Voltage Regulator
LM1117L3
Features
Description
Adjustable or Fixed Output
The LM1117 series of positive adjustable and fixed
Output Current of 1A
regulators are designed to provide 1A with high
Low Dropout, 1.3V max at 1A Output Current
efficiency. All internal circuitry is designed to
0.04% Line Regulation
operate down to 1.3V input to output differential.
0.2% Load Regulation
On-chip trimming adjusts the reference voltage to
100% Thermal Limit Burn-in
1%.
Fast Transient Response
Applications
High Efficiency Linear Regulators
Post Regulators for Switching Supplies
Adjustable Power Supply
Typical Application Data
