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
an in tp lt ag
5 A of output current with a dropout of 250 m V (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.

Frequently Asked Questions
What fixed output voltages are available for TPS755xx regulators?
Fixed options are 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
What packages does the TPS755xx family come in?
It is available in 5-pin TO-220 (KC) and TO-263 (KTT) packages.
How do you disable the TPS755xx regulator?
Apply a TTL high signal to the EN pin to shut it down, reducing quiescent current to <1 μA.
What is the typical dropout voltage of TPS75533 at 5 A?
The typical dropout voltage is 250 mV at 5 A output current.
