78L05

PMIC - Voltage Regulators - Linear

Linear Regulator5V100mASOT-89

The HX78L05 is a 5V, 100mA fixed linear voltage regulator featuring built-in thermal and short-circuit protection.

Best for

  • Low-power 5V supply rails
  • Replacing zener diode-resistor circuits

Avoid if

  • Load current exceeds 100mA
  • High efficiency is required (use switching regulators instead)

Check before use

  • Input voltage headroom
  • Thermal management in SOT-89 package
