RP124x Series 100 mA Ultra-low Supply Current (0.3 A) 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 ) into 1/3 or 1/4. The battery IN 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 A, 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 A Output Voltage Accuracy: 0.8% Output Current: 100 mA Ceramic Capacitor Compatible: 1.0 F or more BM Section DFN1212-6 SOT-23-5 Output Voltage: VIN/3 (RP124xxx3x) 1.2 mm x 1.2 mm x 0.4 mm 2.9 mm x 2.8 mm x 1.1 mm VIN/4 (RP124xxx4x) Supply Current: Typ. 0.1 A Ceramic Capacitor Compatible: 0.1 F to 0.22 F TYPICAL APPLICATIONS RP124 MCU VDD LDO VOUT VCC C IN Battery CE BM ADC Monitor CE control Battery CO UT C BM GND GND The diagram is assumed to be used for RP124xxxxE.
