3 Description

The TPS730 is a low-dropout (LDO) voltage regulator

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 TPS730 offers low

dropout voltages (for example, 120mV typical at

200mA). The low output noise and great PSRR

makes this device designed to power sensitive analog

loads. The TPS730 offers a flexible option for post

regulation with the adjustable capability.
