This device is housed in a DPAK-3 (TO-252) package and operates across a 0\u00b0C ~ +125\u00b0C. It supports a supply voltage range of 4.2V ~ 40V. The device features an output current capability of 1.5A. The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The voltage regulator maintains a constant output voltage by controlling the pass element's resistance in a feedback loop. The error amplifier compares a fraction of the output with an internal reference and adjusts the pass transistor accordingly. For adjustable versions, external resistors set the output voltage. Low dropout architecture enables operation with minimal headroom between input and output.","pin_description":"
