Frequently Asked Questions
What is the output voltage and current rating of the LM7812SX/NOPB?
The LM7812SX/NOPB provides a fixed 12V regulated output voltage with a maximum continuous output current of 1.5A. The output voltage regulation is ±4%, ensuring consistent performance across varying load and temperature conditions.
What input voltage range is required to operate the LM7812SX/NOPB?
The LM7812SX/NOPB requires an input voltage between 7.5V (minimum) and 30V (maximum), with an absolute maximum rating of 35V. A minimum dropout of 2V above the 12V output is needed, so at least 14V input is recommended for stable regulation.
What package type does the LM7812SX/NOPB use, and is it RoHS compliant?
The LM7812SX/NOPB comes in the D²PAK (R-PSSO-G3) 3-pin surface-mount package, which offers excellent thermal dissipation. It is fully RoHS compliant with a Pb-free finish (JESD-609 code e3), making it suitable for modern eco-conscious designs.
What are typical applications for the LM7812SX/NOPB?
Typical applications include linear power supplies for industrial equipment, 12V bias rails in analog and mixed-signal circuits, post-regulators in switching power supplies to suppress output ripple, and voltage regulation in automotive and consumer electronics systems.
