TPS79418DGNT概述

PSRR快速RF低压差稳压器

The TPS794xx family of low-dropout LDO 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, MSOP-8 PowerPAD™ and SOT223-6 packages. Each device in the family is stable with a small 2.2-µF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages for example, 155 mV at 250 mA. Each device achieves fast start-up times approximately 50 µs with a 0.001-µF bypass capacitor while consuming low quiescent current 170 µA typical. Moreover, when the device is placed in standby mode, the supply current is reduced to less than µA. The TPS79428 exhibits approximately 32 µVRMS of output voltage noise at 2.8 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 and low noise features as well as the fast response time.
