A voltage regulator that outputs 12V from higher input voltages. Commonly used
for powering 12V systems and devices.
Description:
The LM7812 is
a popular voltage regulator that provides a stable output voltage of 12
volts. It is part of the LM78xx series of linear voltage regulators, which are
widely used in electronic circuits to provide fixed voltage outputs. Here are
the key features, specifications, and applications of the LM7812:
Key Features:
Output Voltage: 12 V (fixed output).
Input Voltage Range: Typically requires an
input voltage between 14 V to 35 V for stable operation.
Output Current: Can supply up to 1 A of
output current (depending on heat dissipation).
Regulation: Excellent load and line
regulation, ensuring the output voltage remains stable under varying input
conditions and load changes.
Thermal Protection: Built-in thermal
overload protection to prevent damage from overheating.
Short Circuit Protection: Provides
protection against short circuits.
Package: Available in various packages,
including TO-220, TO-263, and others.
Pin Configuration
Input (Vin): Connects to the unregulated
input voltage.
Ground (GND): Connects to the circuit
ground.
Output (Vout): Provides the regulated 12 V
output.
