RP107x SERIES
OUTPUT CAPACITOR-LESS/LOW VOLTAGE 200m A LDO REGULATOR
NO.EA-181-111020
OUTLINE The RP107x Series are CMOS-based LDO regulators featuring 200m A output. Since the output capacitor and noise bypass capacitor are able to be reduced and the packages are small DFN(PLP)1212-6, WLCSP-4-P5, and SC-88A, high density mounting on boards are possible. The input voltage (VIN) is as low as Min.1.4V and the output voltage can be set from 1.0V. Supply current is as low as 9.5μA compared to existing lines. The CE pin can switch the regulator to standby mode.
