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.

[1] The SOA control limits the output current at high voltage differences Vin Vout in order to keep the device in the safe operating area.
[2] During testing low duty cycle pulse techniques are used to maintain the junction temperature as close to ambient as possible.
