说明

The TPS756xx family of 5-A low dropout (LDO) regulators contains four fixed voltage option regulators 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 µA at full load and drops down to less than 1 µA when the device is disabled. The TPS756xx 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 250 mV at an output current of 5 A for the TPS75633) and is directly proportional to the output current.
