APPLICATIONS

DESCRIPTION

The TPS793xx 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 a

small-outline SOT23 package. Each device in the

family is stable, with a small 2.2-

µF ceramic capacitor

on the output. The TPS793xx family uses an advanced,

proprietary BiCMOS fabrication process to yield

extremely low dropout voltages (e.g., 112 mV at

200 mA, TPS79330). Each device achieves fast

start-up times (approximately 50

µs with a 0.001-µF

bypass capacitor) while consuming very low quiescent

current (170

µA typical). Moreover, when the device is

placed in standby mode, the supply current is reduced

to

less

than

1

µA. The TPS79328 exhibits

approximately 32

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.
