RP124N
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 (VIN) 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
