RP116Z SERIES
0.8%ACCURACY 0.7V OUTPUT 400mA LDO REGULATOR
NO.EA-281-131031
OUTLINE
The RP116Z Series are low voltage 400mA voltage regulator. These ICs had been further improved of
low-voltage capability compared with previous low-voltage product.
The input voltage is as low as Min. 1.0V and the output voltage can be set from 0.7V. The output voltage
accuracy has been improved to ±0.8% and due to a built-in transistor with low on-resistance of 0.55Ω (at
VOUT=1.5V).
Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, and
a current limit circuits for over-current for the destruction prevention by the over-current.
The CE pin can switch the regulator to standby mode.
The RP116Z is available in the small and thin WLCSP-4-P7 package (0.69mm square, 0.36mm thickness and
0.4mm pitch), consequently providing a high density mounting.
