The TPS796 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, 3 × 3 VSON, SOT223-6, and TO-263 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, 250 mV
at 1 A). 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 TPS79630 exhibits
approximately 40 µVRMS of output voltage noise at 3.0-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, low noise features, and need fast response
time.
