Power-On Reset With 200-ms Delay Option)

description

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 TPS76850) 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

less than 1

Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery

indicator.

The TPS768xx 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 1.2 V to 5.5 V). Output voltage tolerance is specified

as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP

package.
