500-mA, low-IQ, high-accuracy, adjustable ultra-low-dropout voltage regulator with enable

The TLV758P is an

adjustable 500-mA low-dropout (LDO) regulator . This device is available in a small,

6-pin, 2-mm × 2-mm WSON package and a 5-pin SOT23 package and consumes very low

quiescent current and provides fast line and load transient performance. The TLV758P features an ultra-low dropout of 130 mV at 500 mA that can

help improve the power efficiency of the system.

The TLV758P is

optimized for a wide variety of applications by supporting an input voltage range

from 1.5 V to 6.0 V and an externally adjustable output range of 0.55 V to 5.5 V.

The low output voltage enables this LDO to power the modern microcontrollers with

lower core voltages.

The TLV758P is stable

with small ceramic output capacitors, allowing for a small overall solution size. A

precision band-gap and error amplifier provides high accuracy of 0.7% (max) at 25°C

and 1% (max) over temperature (85°C). This device includes integrated thermal

shutdown, current limit, and undervoltage lockout (UVLO) features. The TLV758P has an internal foldback current limit that helps reduce

the thermal dissipation during short-circuit events.
