概述

The RP105 Series are CMOS-based LDO regulators featuring 400mA output with dual input pin. The input voltage can correspond from 0.9V by the inputting voltage into VBIAS. The UVLO function will lock out the internal circuit, if the input voltage is less than the UVLO voltage. Due to a built-in Nch. transistor with low on-resistance of 0.4Ω (at VSET=0.8V), RP105 provides a low dropout voltage.

RP105 also has an excellent line transient response. In addition to SOT-23-5 package, 1.2mm square DFN(PLP)1212-6 package and DFN1212-5 package are also available.
