Texas Instruments 7812 Linear Voltage Regulator 12V 100mA SOIC-8
Texas Instruments 7812 regulator: fixed 12V output, 100mA, SOIC-8, thermal protection, ±5% tolerance
The Texas Instruments LM78L12ACM/NOPB is a fixed-output, three-terminal positive voltage regulator designed to deliver a stable 12V output at up to 100mA. It serves as a high-performance drop-in replacement for Zener diode and resistor combinations, offering an improvement in output impedance by approximately two orders of magnitude while drawing lower quiescent current.
This regulator is ideal for on-card local regulation, eliminating the distribution issues often associated with single-point regulation. The device includes internal thermal overload protection, output transistor safe-area protection, and an internal short-circuit current limit, ensuring reliable and safe operation under demanding conditions.
Housed in a compact SOIC-8 surface-mount package, it operates over a temperature range of -40°C to +125°C. The output voltage tolerance is ±5% across the full temperature range, and the product is green compliant (no antimony or bromine), meeting modern environmental standards.
Typical applications include power management in industrial systems, localised voltage regulation on PCBs, and general-purpose fixed-voltage power supplies. With its robust feature set and proven Texas Instruments quality, this regulator simplifies power design and enhances system reliability.
