NCP1117, NCV1117  
1.0 A Low−Dropout Positive  
Fixed and Adjustable  
Voltage Regulators  
The NCP1117 series are low dropout positive voltage regulators that  
are capable of providing an output current that is in excess of 1.0 A  
with a maximum dropout voltage of 1.2 V at 800 mA over  
temperature. This series contains eight fixed output voltages of 1.5 V,  
1.8 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V that have no  
minimum load requirement to maintain regulation. Also included is an  
adjustable output version that can be programmed from 1.25 V to  
18.8 V with two external resistors. On chip trimming adjusts the  
reference/output voltage to within ±1.0% accuracy. Internal protection  
features consist of output current limiting, safe operating area  
compensation, and thermal shutdown. The NCP1117 series can  
operate with up to 20 V input. Devices are available in SOT−223 and  
DPAK packages.
