R1154x SERIES
150mA Voltage Regulator (Wide Input Voltage Range)
NO.EA-100-100531
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.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
