DESCRIPTION
The TPS753xxQ and TPS751xxQ devices are
low-dropout regulators with integrated power-on reset
and power-good (PG) functions respectively. These
devices are capable of supplying 1.5 A of output
current with a dropout of 160 mV (TPS75133Q,
TPS75333Q). Quiescent current is 75 μA at full load
and drops down to 1 μA when the device is disabled.
These devices are designed to have fast transient
response for larger load current changes.
Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically
160 mV at an output current of 1.5 A for the
TPS75x33Q) and is directly proportional to the output
current. Additionally, because the PMOS pass
element is a voltage-driven device, the quiescent
current is very low and independent of output loading
(typically 75 μA over the full range of output current,
1 mA to 1.5 A). These two key specifications yield a
significant improvement in operating life for
battery-powered systems.
The device is enabled when EN is connected to a
low-level input voltage. This LDO family also features
a sleep mode; applying a TTL high signal to EN
(enable) shuts down the regulator, reducing the
quiescent current to less than 1 μA at TJ = +25°C.

DESCRIPTION, CONTINUED
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.
