3 Description

The TPS763xx-Q1 family of low-dropout (LDO) linear

voltage regulators supports wide input voltage range

of 2.7V to 10V and up-to 150mA of load current. The

output range is from 1.6V to 5.0V for fixed version,

and 1.6V to 6.5V for adjustable version.

The TPS763xx-Q1 has a ±1.5% output accuracy that

is required for powering digital loads with tight supply

requirements. The internal soft-start circuit reduces

inrush current during start-up (for new chip), thus

allowing for smaller input capacitance.

The TPS763xx-Q1 family of low-dropout (LDO)

voltage regulators offers the benefits of low-dropout

voltage, low-power operation, and miniaturized

packaging. These regulators feature low dropout

voltages and quiescent currents compared to

conventional LDO regulators. Offered in a 5-pin,

small outline integrated-circuit SOT-23 package, the

TPS763xx-Q1 series devices are and excellent choice

for cost-sensitive designs and applications where

board space is at a premium.

The TPS763xx-Q1 also features a logic-enabled sleep

mode to shut down the regulator, reducing quiescent

current to 1μA maximum at TJ = 25°C.
