TPS79618KTTT

PSRR快速RF低压差稳压器

The TPS796 family of low-dropout LDO low-power linear voltage regulators features high power-supply rejection ratio PSRR, ultralow-noise, fast start-up, and excellent line and load transient responses in small outline, 3 × 3 VSON, SOT223-6, and TO-263 packages. Each device in the family is stable with a small, 1-µF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages for example, 250 mV at 1 A. Each device achieves fast start-up times approximately 50 µs with a 0.001-µF bypass capacitor while consuming very low quiescent current 265 µA typical. Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79630 exhibits approximately 40 µVRMS of output voltage noise at 3.0-V output, with a 0.1-µF bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR, low noise features, and need fast response time.
