DESCRIPTION
The TPS758xx family of 3-A low dropout (LDO)
regulators contains four fixed voltage option regu-
lators and an adjustable voltage option regulator.
These devices are capable of supplying 3 A of output
current with a dropout of 150 mV (TPS75833).
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 TPS758xx is designed to have fast transient
response for large load current changes.
