RP106x/RP116Z Series
400mA 1V Input LDO
The RP106x/RP116Z 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 VSET=1.5V), RP106x/RP116Z provides a low dropout voltage. The CE pin can switch the regulator to
standby mode. RP106x/RP116Z has a constant slope circuit. It means a function of soft-start to reduce the inrush current at power on.
In addition to SOT-23-5 and SC-88A packages, 0.69mm square WLCSP-4-P5/P7 packages and a 1.2mm square DFN(PLP)1212-6
package are also available. RP116Z (WLCSP-4-P7) is thiner than RP106Z (WLCSP-4-P5). (t=0.36mm)
