LDK320AM33R General Description

The LDK320 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 18 V, with a typical dropout voltage of 100 mV.It is stabilized with a ceramic capacitor on the output.The very good dynamic characteristic, combined with low drop voltage and low quiescent current make it suitable for low power battery-powered applications.The enable logic control function allows the LDK320 to be in shutdown mode by consuming a total current lower than 1 μA.This device also includes a short-circuit current limiting, thermal and SOA protections.



  • Input voltage from 2.5 to 18 V
  • Very low-dropout voltage (100 mV typ. @ 100 mA load)
  • Low quiescent current (typ. 60 μA, 1 μA in off mode)
  • High PSRR: 88 dB @ 120 Hz
  • Low noise
  • Output voltage tolerance: ± 0.5% @ 25 °C (LDK320A) or ± 2% 25 °C
  • Output current up to 200 mA
  • Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable
  • Logic-controlled electronic shutdown
  • Compatible with ceramic capacitor COUT = 1 μF
  • Current, SOA and thermal protections
  • Available in SOT23-5L and SOT-89 packages
  • Temperature range: -40 °C to 125 °C
