LDK120   Product is in volume production.

200 mA low quiescent current very low noise LDO

データシートのダウンロード

The LDK120 low drop voltage regulator provides 200 mA of maximum current from an input supply voltage in the range of 1.9 V to 5.5 V, with a typical dropout voltage of 100 mV.

It is stabilized with a ceramic capacitor on the output.

The very low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications.

An enable logic control function puts the LDK120 in shutdown mode allowing a total current consumption lower than 1 μA.

The device also includes a short-circuit constant current limiting and thermal protection.

Key Features

  • Input voltage from 1.9 to 5.5 V

  • Very low noise
  • Output voltage tolerance: ± 2.0% @ 25 °C
  • 200 mA guaranteed output current
  • Wide range of fixed output voltages available on request: from 0.8 V to 3.5 V with 100 mV step
  • Adjustable version: from 0.8 V to VIN-Vdrop
  • Logic-controlled electronic shutdown
  • Compatible with ceramic capacitor COUT = 1 μF
  • Internal current and thermal limit
  • Available in SOT23-5L, SOT323-5L and DFN6 (1.2 x 1.3 mm) packages
  • Temperature range: -40 °C to 125 °C
