This device is designed to have a fast transient response and be stable with 10-
µF low ESR capacitors. This
combination provides high performance at a reasonable cost.
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
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 a 20-pin PWP
