78L33 product

78L33

PMIC - Voltage Regulators - Linear

Linear Regulator3.3V100mA

The UMW 78L33 is a 3.3V fixed-output linear voltage regulator capable of delivering up to 100mA.

Best for

  • Low-power 3.3V logic supply
  • General purpose voltage regulation

Avoid if

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

Check before use

  • Input voltage range
  • Thermal dissipation in the chosen package
