LR78L12A product

LR78L12A

PMIC - Voltage Regulators - Linear

Linear Regulator12V100mA

The LR78L12A is a fixed 12V, 100mA positive linear voltage regulator in an SOT-89 package, suitable for low-power applications requiring thermal and short-circuit protection.

Best for

  • Low-power voltage regulation
  • Local regulation on PCBs

Avoid if

  • Current requirements exceed 100mA
  • High efficiency is required (use switching regulators instead)

Check before use

  • Input voltage range
  • Thermal dissipation requirements
