open-in-new Find other Linear regulators (LDO)

Description

TPS777xx and TPS778xx are designed to have a fast transient response and be stable with a 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 260 mV at an output current of 750 mA for the TPS77x33) 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 750 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 1 µA at TJ = 25°C.

The RESET\ output of the TPS777xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS777xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.

Power good (PG) of the TPS778xx is an active high output, which can be used to implement a power-on reset or a low-battery indicator.

The TPS777xx and TPS778xx are offered in 1.5-V, 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V for TPS77701 option and 1.2 V to 5.5 V for TPS77801 option). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS777xx and TPS778xx families are available in 8 pin SOIC and 20 pin PWP packages.
