description

GND/HSINK

The TPS775xx and TPS776xx devices 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.

NC − No internal connection

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 169 mV

at an output current of 500 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 500 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 TPS775xx initiates a reset in microcomputer and microprocessor systems in the event

of an undervoltage condition. An internal comparator in the TPS775xx monitors the output voltage of the

regulator to detect an undervoltage condition on the regulated output voltage.

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 TPS775xx and TPS776xx are offered in 1.5-V, 1.6-V (TPS77516 only), 1.8-V, 2.5-V, 2.8 V (TPS77628 only),

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 TPS77501 option and 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 TPS775xx and TPS776xx families are available

in 20 pin TSSOP package.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
