79L12 product

79L12

PMIC - Voltage Regulators - Linear

Negative RegulatorLinear RegulatorFixed Output

The 79L12 is a standard fixed -12V negative linear voltage regulator capable of delivering up to 100mA of output current in a compact SOT-89 package.

Best for

  • Local on-card voltage regulation
  • Negative rail power supplies

Avoid if

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

Check before use

  • Input voltage range
  • Thermal management for 0.5W dissipation
