RP107N
(SOT-23-5) is the non-promotion product as of April 2017.
RP107x SERIES
OUTPUT CAPACITOR-LESS/LOW VOLTAGE 200mA LDO REGULATOR
NO.EA-181-170424
OUTLINE
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 9.5A compared to existing lines. The CE pin can switch the regulator to standby
mode.

Select (B) without auto-discharge function or (D) with auto-discharge function.
*1
Auto-discharge function quickly lowers the output voltage to 0V by releasing the electrical charge accumulated in the
external capacitor when the chip enable signal is switched from the active mode to the standby mode.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
