RP106x SERIES
0.8%ACCURACY 0.7V OUTPUT 400m A LDO REGULATOR
NO.EA-180-111020
OUTLINE The RP106x Series are low voltage 400m A 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. In addition to SOT-23-5 and SC-88A packages, a 0.69mm square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also available.

Frequently Asked Questions
What type of capacitor is required when using this regulator?
Ceramic capacitors are recommended to be used with this IC, specifically 1.0μF or more.
How can I set the RP106x into standby mode?
The CE pin controls the operation and can switch the regulator into standby mode ("H" Active).
What is the maximum rated output current (I_OUT)?
Under Absolute Maximum Ratings, the specified Output Current ($I_{OUT}$) rating is 500 mA.
If I want to run it at minimum voltage, what are the requirements?
The input voltage range is from 1.0V to 3.6V, and $V_{IN}$ should be set at least 1V above $V_{OUT}$ for operation.
