RP115 Series
Low Voltage 500mA/1A Voltage Regulator (LDO Regulator)

Product Specifications

The RP115 Series are CMOS-based LDO regulators featuring 500mA/1A output.
In the RP115L (DFN1216-8, DFN2020-8B), there are two preset inrush current limit and guaranteed maximum output current values and alternative by the logic of LCON pin.
When LCON pin is set "H", the maximum IOUT=1A and IRUSH=500mA, while LCON pin is set "L", the maximum IOUT=500mA and IRUSH=300mA. (As for the RP115H (SOT-89-5), the preset inrush current limit and output current value is fixed at the maximum IOUT=1A and IRUSH=500mA.)
By this function, for example, in case the RP115L is turned on with setting LCON at "L" (the preset IRUSH=300mA) and after the start up sequence, by making LCON pin at "H" (IOUT=1A), then inrush current can be suppressed less only at start-up.

RP115 supports low voltage, featuring input voltage from 1.4V and output voltage from 0.7V. Due to a built-in Nch. transistor with low on-resistance, RP115 provides a low dropout voltage. Ripple rejection is 75dB and noise is low.
In addition to a fold-back protection circuit built into conventional regulators, RP115 contains a thermal shutdown circuit, an inrush current limit circuit, a constant slope circuit, and a reverse protection circuit.
In addition to SOT-89-5, RP115 is offered in a 1.6mm×1.2mm square DFN1216-8 package for consumer and industrial applications and a DFN2020-8B package for automotive application.
