TPS79133DBVT

The TPS79133DBVT is a Fast RF 100mA Low-dropout Linear Regulator features high power supply rejection ratio (PSRR), ultralow noise, fast start-up and excellent line and load transient responses. Each device in the family is stable, with a small 1µF ceramic capacitor on the output. The TPS79133 uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages. Each device achieves fast start-up times (approximately 63µs with a 0.001µF bypass capacitor) while consuming very low quiescent current (170µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1µA. Applications with analogue components that are noise sensitive, such as portable RF electronics, benefit from the high-PSRR and low-noise features as well as the fast response time.
