商品詳情:
超低噪聲、高 PSRR、快速射頻、高電平啟用的 200mA 低壓降穩(wěn)壓器
描述
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 NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. Each device in the family is stable, with a small 2.2µF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112mV at 200mA, TPS79330). Each device achieves fast start-up times (approximately 50µs with a 0.001µF bypass capacitor) while consuming very low quiescent current (170µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1µA. The TPS79328 exhibits approximately 32µVRMS of output voltage noise at 2.8V output with a 0.1µF 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.
