TLV758P (ACTIVE) Adjustable 500-mA low-dropout (LDO) regulator

 

Description

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 (85ºC). 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.
