UNISONIC TECHNOLOGIES CO., LTD LR1185 Preliminary 150mA CMOS LDO WITH SHUTDOWN AND REFERENCE BYPASS  DESCRIPTION The UTC LR1185 is a 150 mA LDO regulator has very high PSRR and super low dropout voltage especially suitable for wireless and portable applications. In the field of hand-held wireless devices, board space and battery life are the main concerns of designers and end-users. Because of the low quiescent current and low ESR ceramic capacitors, UTC LR1185 can satisfy those concerns. Furthermore, low current consumption (50μA), high output accuracy, current limiting protection, and high ripple rejection ratio are advantages of UTC LR1185. 5  FEATURES * Operating voltage ranges : 2.7V~5.
