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.
