LD39130SJ25R Product Details

The LD39130SJ25R is a high accuracy voltage regulator that provides 300 mA maximum current from an input voltage ranging from 1.4 V to 5.5 V, with a typical dropout voltage of 300 mV.

It is available in DFN6 1.2 x 1.3 mm package and in ultra-small CSP 4 bumps package, allowing the maximum space saving.
The device is stabilized with a ceramic capacitor on the output. The ultra-low drop voltage, low quiescent current and low noise features make it suitable for low power battery-operated applications. It integrates an internal logic circuitry, which allows the regulator to be in ultra-low consumption mode (green mode), when the output current required is very low. The normal working mode, with fast transient response, is restored when the load current increases.
The enable logic control function puts the LD39130SJ25R in shutdown mode allowing a total current consumption lower than 0.1 μA. The current foldback and thermal protection are provided.


  • Input voltage from 1.4 to 5.5 V
  • Ultra low dropout voltage (300 mV typ. at 300 mA load)
  • Automatic green mode
  • Very low quiescent current (1 μA in green mode, 45 μA in normal mode and 0.1 μA typ. in off mode)
  • Output voltage tolerance: ±1.0% at 25 °C
  • 300 mA guaranteed output current
  • Wide range of output voltages available on request: adjustable from 0.8 V, fixed up to 4.0 V in 100 mV step
