L11815AL-XX-TN3-X-R

UNISONIC TECHNOLOGIES CO., LTD L11815A 1.5A CMOS LDO DESCRIPTION The UTC L11815A is a COMS linear regulator. One of it’s feature is very low quiescent current typical as low as 45μA and its dropout voltage is extremely low with 1.5A output current. The internal circuit includes thermal shutdown and current fold-back mechanism to prevent device failure when the circuit is operated in the bad conditions. In application, the UTC L11815A needs a low noise, regulated supply. For stable operation, the output capacitance value should be 4.7μF or more. The UTC L11815A is an ideal for battery applications, such as instrumentations, portable electronics, wireless devices, PC peripherals, and battery powered widgets. The output voltage values are set during manufacturing and the accuracy is tighten 1.5%.
