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.
