The TPS793 is a low-dropout (LDO) voltage regulators that features high power-supply rejection ratio (PSRR), and offers excellent line and load transient responses. This device is stable with a small 2.2µF ceramic capacitor on the output. The TPS793 offers low dropout voltages for example, 112mV (typical) at 200mA. The low output noise and great PSRR makes this device suitable to power sensitive analog loads. The TPS793 offers a flexible option for post regulation with the adjustable capability.
