Description
The RP107 Series are CMOS-based LDO regulators featuring 200 mA output. Since the output capacitor and noise bypass capacitor are able to be reduced and the packages are small WLCSP-4-P5, DFN(PL)1212-6 and SC-88A, high density mounting on boards are possible. The input voltage (VIN) is as low as Min.1.4 V and the output voltage can be set from 1.0 V. Supply current is as low as 9.5µA compared to existing lines. The CE pin can switch the regulator to standby mode.

Typical Application
CIN: 0.1µF
*) The RP107 Series are using an output capacitor as phase compensation to ensure a stable operation even if the output load fluctuates. To reduce the output voltage fluctuation, it is imperative that a 0.1µF to 10µF output capacitor be used. -
