This bination 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 m V at an output current of 1 A for the TPS76850Q1) and is directly proportional to the output current. Additionally, because 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 m A to 1 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a shutdown mode; applying a TTL high signal to the enable (EN) input shuts down the regulator, reducing the quiescent current to less than 1 μA at TJ = 25°C. Power good (PG) is an active-high output, which can be used to implement a power-on reset or a lowbattery indicator. The TPS768xx-Q1 is offered in 1.8-V, 2.5-V, 3.3-V, and 5-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%...
