TPS793475DBVREP

超低噪声，高PSRR ，快速射频200mA的低压差线性稳压器 ULTRALOW-NOISE, HIGH-PSRR, FAST RF 200-mA LOW-DROPOUT LINEAR REGULATORS

The TPS793xx 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-µF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary, BiCMOS fabrication process to yield extremely low dropout voltages e.g., 112 mV at 200 mA, TPS79330. 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 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.
