78L09

Component

Voltage RegulatorLDO9V Output

The 78L09 is a fixed 9V positive voltage regulator in a SOT-89-3L package, capable of delivering up to 100mA output current.

Best for

  • Low-power 9V regulation
  • Space-constrained PCB designs

Avoid if

  • Applications requiring >100mA current
  • High-power dissipation environments without adequate cooling

Check before use

  • Input voltage stability
  • Thermal resistance (RθJA = 166.7°C/W)
