150mA VOLTAGE REGULATOR (Wide Input Voltage Range)
R1154Hxxxx series
I
OUTLINE
The R1154Hxxxx series are CMOS-based voltage regulator (VR) ICs. The R1154Hxxxxx 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 R1154Hxxxx series.
The regulator output voltage is fixed in the R1154HxxxB, while adjustable type is the R1154H001C. Output
voltage accuracy is ±2.0%.
Since the package for these ICs is the SOT-89-5 package with which high density mounting of the ICs on
boards is possible.
