description (continued)

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 T

= 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.
