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 ±1.0% 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.
The NCP1117 series are low‑dropout positive voltage regulators capable of delivering over 1.0 A output current with a maximum dropout of 1.2 V at 800 mA. The family includes nine fixed output versions (1.5 V to 12 V) and an adjustable version programmable from 1.25 V to 18.8 V.
These devices feature internal current limiting, safe‑operating‑area compensation, and thermal shutdown protection. They are supplied in SOT‑223 and DPAK surface‑mount packages and are suitable for consumer, industrial, automotive (NCV prefix) and switching‑power‑supply post‑regulation applications.
