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.
