0 A Low-Dropout Positive Fixed and Adjustable
Voltage Regulators
NCP1117, NCP1117I, NCV1117
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 nine fixed output
voltages of 1.
5 V, 1.
8 V, 1.
9 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.
