RP124x Series

100 mA Ultra-low Supply Current (0.3 µA) LDO Regulator with Battery Monitor

No. EA-503-191025

OVERVIEW

The RP124x is an LDO regulator with a battery monitor (BM) featuring ultra-low supply current.

The battery monitor has a function which divides the input voltage (V_IN) into 1/3 or 1/4. The battery

charge remaining can be monitored by MCU. The buffering output enables directly inputting a signal

into the low voltage A/D converter (ADC) with built-in MCU.

KEY BENEFITS

● Achieving Low Supply Current of 0.3 µA, Longer Battery Life and Downsizing

● Requiring Only Three External Capacitors and Suitable for Space-saving Mounting for the Smaller Packages
