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. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 125 µA 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 (enable) is connected to a high voltage level (> 2 V). Applying a low voltage level (< 0.7 V) to EN shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ = 25°C.

The TPS756xx 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 TPS756xx family is available in a 5-pin TO–220 (KC) and TO–263 (KTT) packages.
