LR1143

UNISONIC TECHNOLOGIES CO., LTD LR1143 LINEAR INTEGRATED CIRCUIT HIGH PSRR, LOW DROPOUT, 400mA ADJUSTABLE LDO REGULATOR  DESCRIPTION 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. The UTC LR1143 consumes typical 0.7μA in shutdown mode. The other features include low dropout voltage, high output accuracy, current limit protection, and enable/shutdown control.  FEATURES * Wide operating voltage range : 3.0V~5.5V * Adjustable output voltage * Enable/shutdown control * Low-noise for RF application * Ultra-Fast response in line/load transient * Current limit protection * Output only 1μF capacitor required for stability *...
