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.
