RP106x Series
400mA 1V Input LDO
The RP106x Series are CMOS-based LDO regulators featuring 400mA output. The input voltage 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), RP106x provides a low dropout voltage. 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 package
are also available.
