description

The TPS757xx family of 3-A low dropout (LDO) regulators contains four fixed voltage option regulators with

integrated power-good (PG) and an adjustable voltage option regulator. These devices are capable of supplying

3 A of output current with a dropout of 150 mV (TPS75733). Therefore, the device is capable of performing a

3.3-V to 2.5-V conversion. Quiescent current is 125

µA at full load and drops down to less than 1 µA when the

device is disabled. The TPS757xx is designed to have fast transient response for large load current changes.
