Description

General part information

LDL112 Series

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.The very low drop voltage, low quiescent current and reverse current protection features make it suitable for low power battery-powered applications.The enable logic control function puts the LDL112 in shutdown mode allowing a total current consumption lower than 1 µA.The device is equipped with current limit and thermal protection.Input voltage from 1.6 to 5.5 VVery low-dropout voltage (300 mV typ. at 1 A load)Low quiescent current (35 µA typ. at no-load, 1 µA max. in off mode)Output voltage tolerance: ± 2.0% at 25 °C1.2 A guaranteed output currentWide range of output voltages available on request: 0.8 V to 5 V with 50 mV step and adjustableLogic-controlled electronic shutdownCompatible with ceramic capacitor COUT= 1 µFInternal current and thermal limitAvailable in DFN6 (2x2), DFN6 (3x3) mm, SO8-batwing and PPAK packagesTemperature range: -40 °C to 125 °CReverse current protectionOutput discharge function (optional)
