R1154x SERIES
150mA Voltage Regulator (Wide Input Voltage Range)
NO.EA-100-120521
OUTLINE
The R1154x series are CMOS-based voltage regulator (VR) ICs. The R1154x 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 R1154x series.
The regulator output voltage is fixed in the R1154xxxxB, while adjustable type is the R1154x001C.
Output voltage accuracy is ±2.0%.
Since the packages for these ICs are DFN1616-6, SOT-23-5, and SOT-89-5, high density mounting of the ICs
on boards is possible.
