The Microchip ATA663201 (voltage regulator) is a fully integrated low-drop voltage regulator, with 3.3V output voltage and 85mA current capability. It is especially designed for the automotive environment. A key feature is that the current consumption is always below 170µA (without load), even if the supply voltage is below the regulator's nominal output voltage. The ATA663201 footprint is compatible to the ATA663231 which enables customers to produce modules with/without LIN transceiver by assembling the LIN SBC (ATA663231) or the standalone LDO (ATA663201).
