RT2519 Description
The RT2519 is a high performance positive low dropout (LDO) regulator designed for applications requiring very low dropout voltage and ultra high Power Supply Ripple Rejection (PSRR) at up to 1A. The input voltage range is from 2.2V to 6V and the output voltage is programmable as low as 0.8V. A P-MOSFET switch provides excellent transient response with just a 4.7μF ceramic output capacitor.
