TPS75833
SLVS330D–JUNE 2001–REVISED MARCH 2004
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 150 mV at
an output current of 3 A for the TPS75833) 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 TPS758xx 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 TPS758xx family is available in a 5-pin TO-220 (KC) and TO-263 (KTT)
packages.
