DESCRIPTIONThe TPS792xx 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 1-μF ceramic capacitor on the output. The
family uses an advanced, proprietary BiCMOS
fabrication process to yield extremely low dropout
voltages (e.g., 55 mV at 100 mA, TPS79230).
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
TPS79228 exhibits approximately 27 μVRMS 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. 100 1 k 10 k
