RP111 Series
Low Voltage Good Load Transient Response 500mA Voltage Regulator (LDO Regulator)

Product Specifications

The RP111 Series are CMOS-based LDO regulators featuring 500mA output current. The minimum input voltage is as low as 1.4V and the output voltage can be set from 0.7V. Due to a built-in 0.46Ω (at VSET=2.8V) on-resistor, RP111 can provide a low dropout voltage. RP111 also features a ripple rejection at 75dB and low noise. The output voltage accuracy is as high as ±0.8%. The accuracy of output voltage of RP111 including the temperature characteristics and the load transient response has been improved.

The Typ. and Max. value of under/overshoot accordnig to the various output current are shown in the typical characteristics in the datasheet, therefore the accuracy of the output voltage estimation will be easy on the actual operating cases. In addition to a fold-back protection circuit built into conventional regulators, RP111 contains a thermal shutdown circuit and an inrush current limit circuit. RP111 is offered in 5-pin SOT-23-5 and 5-pin SOT-89-5 packages. It is also offered in a 6-pin DFN1212-6 package, 1.2 mm x 1.2 mm, for consumer and industrial applications and a 6-pin HSOP-6J package for automotive application.
