Frequently Asked Questions
What is the output voltage of the LM79L12ACM/NOPB?
The LM79L12ACM/NOPB provides a fixed regulated output of -12V. It is a 3-terminal negative voltage regulator designed for applications requiring a stable negative supply rail with minimal external components.
What input voltage range does the LM79L12ACM/NOPB support?
The LM79L12ACM/NOPB supports an input voltage range of -14.5V to -27V, with an absolute maximum rating of -35V. Its dropout voltage is typically 1.7V, so the input must be at least 1.7V more negative than the -12V output.
What are the typical applications for the LM79L12ACM/NOPB?
This device is commonly used in dual-supply analog circuits such as op-amp stages, audio preamplifiers, sensor signal conditioning, and precision instrumentation systems that require a regulated -12V negative power rail alongside a positive supply.
Is the LM79L12ACM/NOPB RoHS compliant and what package does it come in?
Yes, the LM79L12ACM/NOPB is fully RoHS compliant and Pb-free (JESD-609 e3 rated). It is housed in a Small Outline Package (R-PDSO-G8, 8-pin SOIC), suitable for surface-mount assembly on compact PCB designs.
