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 µV_RMS of output voltage noise 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.
