TPS754xxQ

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007

The RESET (SVS, POR, or power on reset) output of the TPS752xxQ initiates a reset in microcomputer and

microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS752xxQ

monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.

When the output reaches 95% of its regulated voltage, RESET goes to a high-impedance state after a 100-ms

delay. RESET goes to a logic-low state when the regulated output voltage is pulled below 95% (that is, during an

overload condition) of its regulated voltage.

The TPS754xxQ has a power good terminal (PG) as an active high, open drain output for use with a power-on

reset or a low-battery indicator.

The TPS754xxQ and TPS752xxQ are 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 1.5 V to 5 V). Output voltage tolerance is specified as a

maximum of 2% over line, load, and temperature ranges. The TPS754xxQ and TPS752xxQ families are

available in a 20-pin TSSOP (PWP) package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage to the device. Exposure to absolute maximum conditions for extended

periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other

conditions beyond those specified is not implied.
