Description
RP111x Series Good Transient Response Low Voltage 500mA LDO NO.
EA-241-150204 OUTLINE The RP111x Series are CMOS-based LDO regulators featuring 500mA output current.
The 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 an excellent line transient response, ripple rejection at 75dB, and low noise.
The output voltage accuracy is as high as ±0.
8% and the temperature drift coefficient of output voltage is low at ±30ppm/C.
The accuracy of the output voltage of RP111x includes the temperature characteristics and the load transient response has been improved.
The typ.
and max value of under/overshoot for 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.
SOT-23-5 and SOT-89-5 packages, a 1.
2mm square DFN1212-6 package are available.
