L78L33ABUTR

Voltage Regulators - Linear

Linear Regulator3.3V100mASOT-89

The L78L33ABUTR is a reliable 3.3V, 100mA fixed linear voltage regulator in a SOT-89 package, ideal for local on-card regulation.

Best for

  • Local voltage regulation
  • Noise-sensitive circuits
  • Low-power embedded systems

Avoid if

  • Output current requirements exceed 100mA
  • High efficiency is critical (use switching regulators instead)

Check before use

  • Thermal dissipation requirements
  • Input voltage headroom
