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 µV_RMS 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.

TIDA-00431 — 参考设计 - 采用 8GHz 直流耦合全差分放大器的 RF 采样 4GSPS ADC

宽带射频 (RF) 接收器有助于极大提升无线电设计中的灵活性。较宽的瞬时带宽支持灵活调节而无需改动硬件且能够以间隔较大的频率捕获多个通道。

此参考设计介绍了一个宽带射频接收器，该接收器利用 4 GSPS 模数转换器 (ADC) 并具有一个 8GHz 直流耦合全差动放大器前端。放大器前端提供信号增益并允许采集下行到直流的信号，而平衡-非平衡变压器耦合输入则做不到这一点。
