SLVS389M – SEPTEMBER 2002 – REVISED SEPTEMBER 2015 TPS786 Ultralow-Noise, High-PSRR, Fast, RF, 1.5-A
Low-Dropout Linear Regulators
1 Features 3 Description The TPS786 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, SOT223-6 and DDPAK-5 packages.
Each device in the family is stable, with a small 1-ОјF
ceramic capacitor on the output. The family uses an
advanced, proprietary BiCMOS fabrication process to
yield extremely low dropout voltages (for example,
390 mV at 1.5 A). Each device achieves fast start-up
times (approximately 50 Ојs with a 0.001-ОјF bypass
capacitor) while consuming very low quiescent
current (265 ОјA, typical). Moreover, when the device
is placed in standby mode, the supply current is
reduced to less than 1 ОјA. The TPS78630 exhibits …
