Semiconductor
S1117AQ/S1117-xxQ
Adjustable and Fixed LDO Voltage
Regulator
Descriptions
The S1117A and S1117 series of positive adjustable and fixed
regulators are designed to provide 1A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1.3V input to output differential. On-Chip trimming adjusts reference Voltage to 2%
Features
Output Current of 1A 1.3V Maximum Dropout voltage at 1A Output Current 100% Thermal Limit Burn-In Fast Transient Response
