RT2519W
RT2519W is Low-Dropout Linear Regulator manufactured by Richtek.
Description
The RT2519W 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. The external enable control effectively reduces power dissipation while shutdown and further output noise immunity is achieved through bypass capacitor on NR pin. Additionally, the RT2519W features a precise 3% output regulation over line, load, and temperature variations. The device is available in the VDFN-8AL 3x3 package and is specified from
- 40°C to 125°C.
