3 Description

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.
