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.
