FEATURES
DESCRIPTION
D
Qualified For Automotive Applications
ESD Protection Exceeds 2000 V Per
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
