SLVS325D – MARCH 2001 – REVISED FEBRUARY 2018 TPS791
Ultralow Noise, High PSRR, Fast RF 100-mA Low-Dropout Linear Regulators
1 Features 3 Description The TPS791 device is a low-dropout (LDO) lowpower linear voltage regulator that 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. The
device is stable, with a small 1-ВµF ceramic capacitor
on the output. The TPS791 uses an advanced,
proprietary BiCMOS fabrication process to yield
extremely low dropout voltages (for example, 38 mV
at 100 mA, TPS79147). This device achieves fast
start-up times (approximately 63 Вµs with a 0.001-ВµF
bypass capacitor) while consuming very low
quiescent current (170 ВµA typical). Moreover, when
the device is placed in standby mode, the supply
current is reduced to less than 1 ВµA. The TPS79118
exhibits approximately 15 ВµVRMS of output voltage …
