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. 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, 1 mA to 7.5 A). 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 µA 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 TPS759xx 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 TPS759xx family is available in a 5-pin TO–220 (KC) and TO–263 (KTT) packages.
