DescriptionThe 79325-Q1 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 a small-outline SOT23 package. Each device in the family is stable, with a small 2.2-F ceramic capacitor on the output. The 79325-Q1 family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 112 mV at 200 mA, TPS79330). Each device of the 79325-Q1 achieves fast start-up times (approximately 50 s with a 0.001-F bypass capacitor) while consuming very low quiescent current (170 A typical). Moreover, when the device is placed in standby mode, the supply current of the 79325-Q1 is reduced to less than 1 A. The TPS79328 exhibits approximately 32 VRMS of output voltage noise 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.
