TPS79530

The TPS79530 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 a small outline, SOT223-6, package.Each device in the family is stable with a small 1-F ceramic capacitor on the output. The TPS79530 uses an advanced, proprietary BiCMOS fabrication process to advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example 110 mV at 500 mA). Each device achieves fast start-up times (approximately 50 s with a 0.001-F bypass capacitor) while consuming very low quiesc ent current (265 A typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 A. The TPS79530 exhibits 3.0 V output with a 0.1-F bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR and low noise features, as well as the fast response time.
