description
This device is designed to have an ultra-low quiescent current and be stable with a 4.7-µF capacitor. 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 85 mV
at an output current of 150 mA for the TPS76550) 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 35 µA over the full range of output current, 0 mA to 150 mA). 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 µA (typ).

description (continued)
Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery
indicator.
The TPS765xx 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 1.25 V to 5.5 V). Output voltage tolerance is specified
as a maximum of 3% over line, load, and temperature ranges. The TPS765xx family is available in 8 pin SOIC
package.
