description

The TPS755xx family of 5-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

5 A of output current with a dropout of 250 mV (TPS75533). 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 TPS755xx is designed to have fast transient response for large load current changes.
