Description

The RRP51045 is an ultra-low noise, high PSRR, low dropout regulator capable of sourcing up to 4A of load current with only 250mV dropout voltage. It operates from an input voltage of 1.1V for extremely low voltage applications to 6.5V.

The LDO output voltage can be programmed from 0.5V to 2.075V using voltage setting pins on the IC in 25mV steps, eliminating the need for traditional external feedback resistors and saving PCB space. External feedback resistors can still be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.5V to 5.1V.
