TPS77615-EP Datasheet | Texas Instruments

description The TPS776xx devices are designed to have a fast transient response and be stable with a 10-µF low ESR capacitors. 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 169 m V at an output current of 500 m A for the TPS77633) 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 m A to 500 m 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 1 µA at TJ = 25°C. Power good (PG) of the TPS776xx is an active high output, which can be used to implement a power-on reset or a low-battery indicator. The TPS776xx are offered in 1.5-V, 1.8-V, 2.5-V, 2.8 V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.2 V to 5.5 V for TPS77601 option). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS776xx family is available in 20 pin TSSOP package.
