The TPS795 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 small outline, 6-pin SOT-223 and 3-mm × 3-mm VSON packages. 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 (for
example, 110 mV at 500 mA). Each device achieves fast start-up times (approximately
50 µs with a 0.001-µF bypass capacitor) while consuming very low quiescent current
(265 µA, typical). Moreover, when the device is placed in standby mode, the supply current is
reduced to less than 1 µA. The TPS79530 device exhibits approximately
33 µVRMS of output voltage noise at 3-V output 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 from the fast response
time.
