DESCRIPTION

The TPS756xx family of 5-A low dropout (LDO)

regulators contains four fixed voltage option regu-

lators and an adjustable voltage option regulator.

These devices are capable of supplying 5 A of output

current with a dropout of 250 mV (TPS75633).

Therefore, the device is capable of performing a

3.3-V to 2.5-V conversion.

Quiescent current is 125 碌A at full load and drops

down to less than 1 碌A when the device is disabled.

The TPS756xx is designed to have fast transient

response for large load current changes.
