L78L12AC - Positive Voltage Regulators

Download the L78L12AC datasheet PDF (L78L33C included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for positive voltage regulators.

Description

The L78L series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible.

If adequate heat-sink is provided, they can deliver up to 100 mA output current.

Features

  • Output current up to 100 mA.
  • Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overload protection.
  • Short-circuit protection.
  • No external components are required.
  • Available in either ± 4% (A) or ± 8% (C) selection.

TO-92 SO-8 SOT-89 Maturity status link L78L L78L Datasheet Positive voltage regulators Features • Output current up to 100 mA • Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overload protection • Short-circuit protection • No external components are required • Available in either ± 4% (A) or ± 8% (C) selection Description The L78L series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation.
