150mA VOLTAGE REGULATOR (Wide Input Voltage Range)
R1154Xxxxx series
I
OUTLINE
The R1154Xxxxx series are CMOS-based voltage regulator (VR) ICs. The R1154Xxxxxx has features of 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 R1154Xxxxx series.
The regulator output voltage is fixed in the R1154XxxxB, while adjustable type is the R1154X001C (Under
Development). Output voltage accuracy is ±2.0%.
Since the packages for these ICs are the SOT-89-5 package with which high density mounting of the ICs on
boards is possible and SC-84-5 (Under Development) with large power dissipation.
