LDL112   Product is in volume production.

1.2 A low quiescent current LDO with reverse current protection

Download Datasheet

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.

Key Features

  • Input voltage from 1.6 to 5.5 V
  • Very 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 °C
  • 1.2 A guaranteed output current
  • Wide range of output voltages available on request: 0.8 V to 5 V with 50 mV step and adjustable
  • Logic-controlled electronic shutdown
  • Compatible with ceramic capacitor COUT = 1 µF
  • 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)
