TPS753xxQ
SLVS241C – MARCH 2000 – REVISED OCTOBER 2007
For the TPS751xxQ, the power-good terminal (PG) is an active high, open drain output for use with a power-on
reset or a low-battery indicator.
The RESET (SVS, POR, or power on reset) output of the TPS753xxQ initiates a reset in microcomputer and
microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS753xxQ
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 TPS751xxQ and TPS753xxQ 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 TPS751xxQ and TPS753xxQ 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.
