R1154x Series
150 mA Voltage Regulator (Wide Input Voltage Range)
No. EA-100-171024
OUTLINE
The R1154x is a voltage regulator (VR) featuring 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.
The regulator output voltage is fixed in the R1154xxxxB, while adjustable type is the R1154x001C. The 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.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
conditions.
