TPS79318DBVRG4Q1 Part Information

Details for TPS79318DBVRG4Q1 by Texas Instruments

Semiconductors - ICs>Power Management ICs - PMIC>Voltage Regulators

Part Description

The TPS793xx-Q1 family of low-dropout (LDO) lowpower linear voltage regulators features high powersupply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in a small-outline SOT-23 package. Each TPS793-Q1 device in the family is stable, with a small 2.2-μF ceramic capacitor on the output. The TPS793xx-Q1 family uses an advanced, proprietary, BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112 mV at 200 mA, TPS79330-Q1). Each device achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor), while consuming very low quiescent current (170 μA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 μA. The TPS79328-Q1 exhibits approximately 32 μVRMS of output voltage noise with a 0.1-μF 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.
