S1117APIC/S1117-xxPIC
Adjustable and Fixed Voltage Regulator
Descriptions
The S1117 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 reference voltage to 2%.
Features
• Adjustable or fixed output • Output current of 1A • Low dropout, 1.3V maximum at 1A output current • Thermal shutdown protection
