The TPS796-Q1 low-dropout (LDO), low-power, linear voltage regulator features high power-supply rejection ratio (PSRR), ultra-low-noise, fast start-up, and excellent line and load transient responses. This device is stable with a small 1µF ceramic capacitor on the output.

The low output noise and great PSRR performance make the device designed to power-sensitive analog loads. The TPS796-Q1 is a flexible device for post regulation because this device supports an input voltage range from 2.7V to 5.5V.
