RICOH RP111x Series Good Load Transient Response Low Voltage 500mA LDO handbook
The RP111x 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 VOUT=2.8V) on-resistor, RP111x can provide a low dropout voltage. RP111x 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 RP111x including the temperature characteristics and the load transient response has been improved. The Typ. and Max value of under/overshoot according 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, RP111x contains a thermal shutdown circuit and an inrush current limit circuit. In addition to SOT-23-5 and SOT-89-5 packages, a 1.2mm square DFN1212-6 package is also available. Ceramic capacitors can be used.
