LR1142 CMOS IC
HIGH PSRR, LOW DROPOUT, 500mA ADJUSTABLE LDO REGULATOR
DESCRIPTION
The UTC LR1142 is a CMOS-based 500mA 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 LR1142 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.
The UTC LR1142 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
LR1142 CMOS集成電路
高 PSRR、低壓差、500mA 可調節 LDO 穩壓器
描述
UTC LR1142 是一款基於 CMOS 的 500mA 穩壓器，具有低電源電流、低壓差、可調輸出電壓，該器件提供高 PSRR 和低壓差。 靜態電流低至35μA，進一步延長電池壽命。 UTC LR1142 還可與低 ESR 陶瓷電容器配合使用，從而減少電源應用所需的電路板空間，這對於手持無線設備至關重要。
UTC LR1142 在關斷模式下的典型功耗為 0.7μA。 其他特性包括低壓差電壓、高輸出精度、限流保護和啟用/關斷控制。
