Texas Instruments  TPS75501KC

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 uA at full load and drops down to less than 1 uA when the device is disabled. The TPS755xx 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 TPS75533) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 125 uA over the full range of output current). These two key specifications yield a significant improvement in operating life for battery-powered systems.

The device is enabled when EN\ is connected to a low-level voltage. This LDO family also features a sleep mode; applying a TTL high signal to EN\ (enable) shuts down the regulator, reducing the quiescent current to less than 1 uA at TJ = 25°C. The power-good terminal (PG\) is an active low, open drain output, which can be used to implement a power-on reset or a low-battery indicator.

The TPS755xx is offered in 1.5-V, 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.22 V to 5 V). Output voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The TPS755xx family is available in a 5-pin TO\x96220 (KC) and TO\x96263 (KTT) packages.
