description (continued)

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% (i.e., over load condition)

of its regulated voltage.

The TPS751xxQ or TPS753xxQ 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 1.5 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 20-pin TSSOP (PWP) packages.
