        1A低輟學率精密調節器--AT1117

        亚投彩神分類: 穩壓管 LDO
          The AT1117 is a positive low dropout regulator designed toprovide up to 1A of output current. The device is available in an adjustable version and fixed output voltages of 1.5V to 5V. All internal circuitry is designed to operate down to 1.2V input to output differential.Dropout voltage is guaranteed at a typical of 1.2V at 1A, decreasing at lower load currents.

            一 概述

            The AT1117 is a positive low dropout regulator designed to provide up to 1A of output current. The device is available in an adjustable version and fixed output voltages of 1.5V to 5V. All internal circuitry is designed to
            operate down to 1.2V input to output differential. Dropout voltage is guaranteed at a typical of 1.2V at 1A, decreasing at lower load currents.On chip trimming adjusts the reference/output voltage to within ±2%. Current limit
            is also trimmed in order to minimize the stress on both the regulator and the power source circuitry
            under overload conditions. The low profile surface mount SOT-89, SOT-223 and TO-252 package allows the device to be used in applications where space is limited. The AT1117 requires an output capacitance for stability.Output stability.Output capacitors of this size or larger are normally included in most regulator designs.
