LD39115J   Product is in volume production.

150 mA low quiescent current low noise voltage regulator

Download Datasheet

The LD39115J provides 150 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 80 mV. It is stabilized with a ceramic capacitor. The ultra low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications. Power supply rejection is 65 dB at low frequencies and starts to roll off at 10 kHz. An enable logic control function puts the LD39115J 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 1.5 to 5.5 V
  • Ultra low dropout voltage (80 mV typ. at 100 mA load)
  • Very low quiescent current (20 μA typ. at no load, 35 μA typ. at 150 mA load, 1 μA max in off mode)
  • Very low noise (33 μVRMSfrom 1 kHz to 100 kHz at VOUT= 1.8 V)
  • Output voltage tolerance: ± 2.0 % @ 25 °C
  • 150 mA guaranteed output current
  • Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step
  • Logic-controlled electronic shutdown
  • Compatible with ceramic capacitor COUT= 1 μF
  • Internal current and thermal limit
  • Flip-chip 4 bumps 0.8 x 0.8 mm. pitch 0.4 mm
  • Temperature range: -40 °C to 125 °C
