description (continued)
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 230 mV at an output
current of 1 A for the TPS76750) 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 85
µA over
the full range of output current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life
for battery-powered systems. 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 1
µA at TJ = 25°C.
The RESET output of the TPS767xx initiates a reset in microcomputer and microprocessor systems in the event of an
undervoltage condition. An internal comparator in the TPS767xx monitors the output voltage of the regulator to detect an
undervoltage condition on the regulated output voltage.
The TPS767xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and in an
adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is specified as a maximum
of 2% over line, load, and temperature ranges. The TPS767xx family is available in 8-pin SOIC and 20-pin PWP packages.

The TPS76701 is programmable using an external resistor divider (see application
information). The D and PWP packages are available taped and reeled. Add an R
suffix to the device type (e.g., TPS76701QDR).
