Because the PMOS device behaves as a low-value
NC − No internal connection
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 low-dropout (LDO) family also features a sleep mode; applying a TTL high
signal to the enable (EN) input shuts down the regulator, reducing the quiescent current to 1 µA at T_J = 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-V, 3.3-V, and 5-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
package.
