The TPS796xx 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 x 3 SON, SOT223-6, and DDPAK-5 packages. Each device in the family is stable with a small 1F 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 50s with a 0.001F bypass capacitor) while consuming very low quiescent current (265 A typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1A. The TPS79630 exhibits approximately 40VRMS of output voltage noise at 3.0V output, with a 0.1F bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR, low noise features, and the fast response time.
