RP154 Series
Low Voltage Dual 300mA Voltage Regulator (LDO Regulator)

Product Specifications

The RP154 Series are CMOS-based dual output LDO regulators featuring 300mA output. RP154 features a supply current from 50µA per output, a minimum input voltage from 1.4V and the output voltage can be set from 0.8V to 3.7V (in 0.1V steps).

The RP154 is offered in a 6-pin SOT-23-6 package for a single input type and 8-pin DFN1216-8 and DFN2020-8 packages for a dual input type.
Due to the low minimum input voltage RP154 is able to extend battery life, additionally the LDO has less power dissipation by the low dropout voltage between input and output.
