TPS79625KTTRG3 Description
The TPS796xx family of low-dropout (LDO) low-power linear voltage regulators features a high power supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in small outline, 3 x 3 SON, SOT223-6, and DDPAK-5 packages. Each device in the family is
stable with a small 1μF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low
dropout voltages (for example, 250mV at 1A). Each device achieves_ fast start-up times (approximately 50μs with a 0.001μF 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 1μA. The TPS79630 exhibits approximately 40μVRMs of output voltage noise at 3.0V output, with a 0.1μF bypass capacitor. Applications with analog
components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR, low noise features, and fast response time.
