DESCRIPTION
The TPS759xx family of 7.5-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
7.5 A of output current with a dropout of 400 mV (TPS75933). Therefore, the devices are capable of performing a
3.3-V to 2.5-V conversion. Quiescent current is 125 µA at full load and drops below 10 µA when the devices are
disabled. The TPS759xx is designed to have fast transient response for large load current changes.
