LDL112 1.2 A low quiescent current LDO with reverse current protection Datasheet - production data Applications Consumer Computer Battery-powered systems Low voltage point-of-load USB-powered devices Description The LDL112 is a low-dropout linear regulator, which can provide a maximum current of 1.2 A, with a typical dropout voltage of 300 mV. It is stabilized with a ceramic capacitor on the output. Features The very low drop voltage, low quiescent current Input voltage from 1.6 to 5.5 V and reverse current protection features make it Very low-dropout voltage (300 mV typ. at suitable for low power battery-powered 1 A load) applications. Low quiescent current (35 A typ. at no-load, 1 A max. in off mode) The enable logic control function puts the Output voltage tolerance: 2.0% at 25 C LDL112 in shutdown mode allowing a total 1.2 A guaranteed output current current consumption lower than 1 A. Wide range of output voltages available on The device is equipped with current limit and request: 0.8 V to 5 V with 50 mV step and thermal protection. adjustable Logic-controlled electronic shutdown Compatible with ceramic capacitor COUT = 1 F Internal current and thermal limit Available in DFN6 (2x2), DFN6 (3x3) mm, SO8-batwing and PPAK packages Temperature range: -40 C to 125 C Reverse current protection Output discharge function (optional) October 2016 DocID026319 Rev 2 1/32 www.st.com This is information on a product in full production.
