3 Description
The TPS794 low-dropout (LDO) linear voltage
regulator features high power-supply rejection ratio
(PSRR), low-noise, fast start-up, and excellent line
and load transient responses. Each device in the
family is stable with a small 2.2μF ceramic capacitor
on the output. The TPS794 offers low dropout
voltages, 155mV (typ) at 250mA.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.
