说明

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 uA 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.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 400 mV at an output current of 7.5 A for the TPS75933) and is directly proportional to the output current.
