LR1143 Overview
The UTC LR1143 is a CMOS-based 400mA voltage regulator with low supply current, low dropout, adjustable output voltage, The device offering high PSRR and low dropout. The quiescent current is as low as 35μA, further prolonging the battery life. The UTC LR1143 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.
