Low Voltage 1A LDO Regulator
The RP131 Series are CMOS-based LDO regulators featuring 1A output with low on-resistance. The CMOS process provides both large output current and low supply current. The dropout voltage is significantly lower than bipolar regulators.
The RP131 handles low voltage with an input voltage from 1.6V and an output voltage from 0.8V. Accordingly, the device supports highly integrated, low voltage-driven LSI as a rear stage of the DC/DC converter. The CE pin can switch the regulator into standby mode. In addition to a fold-back protection circuit built into conventional LDO regulators, RP131 has a thermal shutdown circuit and inrush current limit circuit.
