RICOH RP108J SERIES Low Input Voltage 3A LDO Regulator handbook

The RP108J Series are CMOS-based voltage regulator ICs featuring 3A output with low ON-resistance. Each IC of this series consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a fold-back protection circuit, and a thermal shutdown circuit. This series features both low supply current and high output current, and the dropout voltage is much smaller than bi-polar's. The minimum input voltage is as low as 1.6V and the output voltage can be set from 0.8V, therefore it can be connected with the DC/DC converter as the latter power supply for high density LSI that is operated by low output voltage. The output voltage of RP108J081x is externally adjustable by using external divide resistors. The CE pin of the RP108J Series can switch the regulator to standby mode. In addition to a fold-back protection circuit, which is already built in the conventional regulators, this series contain a thermal shutdown circuit, a constant slope circuit as a soft-start function and a reverse current protection circuit. Ceramic capacitors can be used.
