TPS79628KTTTG3 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. 3 SON, SOT223-6, and DDPAK-5 packages. Each device in the family is stable with a small 1xF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g, 250mV at 1A). Each device achieves fast start-up times (approximately 50xs with a 0.001xF bypass capacitor) while consuming very low quiescent current (265 cA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 10A. The TPS79630 exhibits approximately 40xVpus of output voltage noise at 3.0V output, with a 0. 1cF 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.
