78L33B - POSITIVE VOLTAGE REGULATORS

Download the 78L33B datasheet PDF. This datasheet also covers the 78L05ABUTR variant, as both devices belong to the same positive voltage regulators family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.

L78L Positive voltage regulators Datasheet - production data 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 oncard regulation for elimination of noise and distribution problems associated with single-point regulation.
