TPS79318DBVRQ1

超低噪声，高PSRR FAST -RF 200 mA低压降线性稳压器 ULTRALOW-NOISE HIGH-PSRR FAST-RF 200-mA LOW-DROPOUT LINEAR REGULATORS

The TPS793xx-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 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.
