TPS79518DCQR

The TPS79518DCQR is a 1.8V fixed output low-power low-dropout (LDO) Linear Regulator features high power-supply rejection ratio (PSRR), ultralow noise, fast start-up and excellent line and load transient responses. The device is stable with a small 1µF ceramic capacitor on the output. The device uses an advanced, proprietary BiCMOS fabrication process to yield extremely low-dropout (LDO) voltages. The device achieves fast start-up times while consuming very low quiescent current. Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1µA. Applications with analog components that are noise-sensitive, such as portable RF electronics, benefit from the high-PSRR and low-noise features, as well as from the fast response time.
