SLVS329C – JUNE 2001 – REVISED MARCH 2004

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 T

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.
