RP115L111B Datasheet | RICOH

RP115x SERIES Low On Resistance/ Low Voltage 1ch 500m A/ 1.0A Alternative LDO NO. EA-274-141205 OUTLINE The RP115x Series are CMOS-based positive voltage regulators featuring 500m A/ 1.0A that provide high ripple rejection, low dropout voltage, high output voltage accuracy, and low supply current. Internally, the RP115x Series consist of a voltage reference unit, an error amplifier, a resistor-net for output voltage setting, a current limit circuit, a thermal shutdown circuit, and a reverse current protection circuit. The RP115x Series uses CMOS process for achieving low supply current, low On Resistance for low dropout voltage (TYP. 0.195V (DFN1216-8, IOUT=1.0A, VSET=1.2V)) and CE function for long battery life. Excellent ripple rejection, input transient response, and load transient response make this series ideal for the power sources of mobile munication equipments. The RP115x Series are available in the DFN1216-8 package for space saving and the SOT-89-5 (Output current: 1.0A fixed) package for higher power applications. The RP115L Series (DFN1216-8 package) can choose the output current limit between 1.0A or 500m A by alternating the LCON pin between “H” or “L”. The RP115H Series (SOT-89-5 package) can output only 1.0A since it does not include the LCON pin. Features - Supply Current - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -...
