3 Description

The TPS793xx-Q1 family of low-dropout (LDO) lowpower

linear voltage regulators features high powersupply

rejection ratio (PSRR), ultralow noise, fast

start-up, and excellent line and load transient

responses in a small-outline SOT-23 package. Each

TPS793-Q1 device in the family is stable, with a small

2.2-μF ceramic capacitor on the output. The

TPS793xx-Q1 family uses an advanced, proprietary,

BiCMOS fabrication process to yield extremely low

dropout voltages (for example, 112 mV at 200 mA,

TPS79330-Q1). 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.
