SUPPORTS DEFENSE, AEROSPACE,
AND MEDICAL APPLICATIONS
The TPS791xx 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., 38 mV at
100 mA, TPS79147). Each device achieves fast
start-up times (approximately 63 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 TPS79118
exhibits approximately 15 µV_RMS 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.
