TPS79147DBVREP

超低噪声，高PSRR ，快速射频， 100mA低压降线性稳压器 ULTRALOW NOISE, HIGH PSRR, FAST RF, 100-mA LOW-DROPOUT LINEAR REGULATORS

The TPS791xx 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 1-µF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages e.g., 38 mV at 100 mA, TPS79147. Each device achieves fast start-up times approximately 63 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 TPS79118 exhibits approximately 15 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.
