The TPS755xx family of 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 5 A of output current with a dropout of 250 mV (TPS75533). 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 TPS755xx is designed to have fast transient response for large load current changes.
The TPS755xx family of 5-A low dropout (LDO) regulators includes four fixed voltage option regulators with integrated power-good (PG) and an adjustable voltage option regulator. These devices are capable of supplying 5 A of output current with a dropout of 250 mV for the TPS75533 model. The family is designed to have fast transient response for large load current changes and features thermal shutdown protection.
