NX1117C; NX1117CE series
Low-dropout linear regulators
Rev. 2 — 11 December 2012 Product data sheet
1. General description
The NX1117C/NX1117CE are two series of low-dropout positive voltage regulators with an output current capability of 1 A. The two series consist of 18 fixed output voltage versions and two adjustable output voltage versions. NX1117C series offers an output voltage accuracy of 1 % and NX1117CE series of 1.25 %. The regulators feature output current limiting, Safe Operating Area (SOA) control, and thermal shutdown. The NX1117C/NX1117CE series are housed in a medium power SOT223 (SC-73) Surface-Mounted Device (SMD) plastic package.
