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 verylow quiescent current and provides fast line and load transient performance. TheTLV758P features an ultra-low dropout of 130 mV at 500 mA that can helpimprove the power efficiency of the system.

The TLV758P is optimized for a wide variety of applications bysupporting an input voltage range from 1.5 V to 6.0 V and an externally adjustable output range of0.55 V to 5.5 V. The low output voltage enables this LDO to power the modern microcontrollers withlower core voltages.

The TLV758P is stable with small ceramic output capacitors, allowingfor a small overall solution size. A precision band-gap and error amplifier provides high accuracyof 0.7% (max) at 25°C and 1% (max) over temperature (85ºC). This device includes integrated thermalshutdown, current limit, and undervoltage lockout (UVLO) features. The TLV758Phas an internal foldback current limit that helps reduce the thermal dissipation duringshort-circuit events.
