RP107x Series
Output Capacitor-less 200mA LDO
The RP107x Series are CMOS-based LDO regulators featuring 200mA 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 (V
IN
) 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.
