RP124L283E Datasheet | RICOH

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 KEY SPECIFICATIONS PACKAGES LDO Section - Input Voltage Range: 1.7 V to 5.5 V - Supply Current: Typ. 0.2 μA - Output Voltage Accuracy: ±0.8% - Output Current: 100 m A - Ceramic Capacitor patible: 1.0 μF or more BM Section - Output Voltage: VIN/3 (RP124xxx3x) VIN/4 (RP124xxx4x) - Supply Current: Typ. 0.1 μA - Ceramic Capacitor patible: 0.1 μF to 0.22 μF DFN1212-6 1.2 mm x 1.2 mm x 0.4 mm TYPICAL APPLICATIONS Battery CIN CE CE control RP124 - MCU VOUT Battery Monitor BM COUT ADC GND SOT-23-5 2.9 mm x 2.8 mm x 1.1 mm The diagram is assumed to be used for RP124xxxx E.
