Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

description
The TPS753xxQ and TPS751xxQ 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. TPS751xxQ and TPS753xxQ 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, since 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 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.
For the TPS751xxQ, the power-good terminal (PG) is an active high, open drain output, which can be used to
implement a power-on reset or a low-battery indicator.

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.
