Low Consumption VOLTAGE REGULATOR
(Operating Voltage up to 36V)
R1514x SERIES
OUTLINE
NO. EA-152-070328
The R1514x series are CMOS-based positive voltage regulator (VR) ICs. The R1514xxxxxx has features of
high input voltage operating, high output voltage accuracy and ultra-low supply current. A peak current limit
circuit, a short current limit circuit, and a thermal shutdown circuit are built in the R1514x series.
The regulator output voltage is fixed in the R1514xxxxB. Output voltage accuracy is ±2.0%.
Since the packages for these ICs are the SOT-89-5 and HSOP-6J, high density mounting of the ICs on boards
is possible.
