Frequently Asked Questions
What is the input voltage range of the LM2842XMK-ADJL?
The LM2842XMK-ADJL accepts an input voltage from 4.5V to 42V, with a nominal 12V operating point. This wide range makes it suitable for 12V automotive rails, 24V industrial bus systems, and unregulated wall adapters up to 42V.
How is the output voltage set on the LM2842XMK-ADJL?
Output voltage is set by an external resistor divider connected to the ADJ pin. The internal reference voltage is 0.765V, so selecting appropriate top and bottom resistors programs any output voltage above that threshold, giving designers full flexibility for 1.8V, 3.3V, 5V, or other rails.
What package does the LM2842XMK-ADJL use and what are its dimensions?
The LM2842XMK-ADJL is housed in a SOT-23-6 (TSOT-6) 6-pin surface-mount package with JESD-30 code R-PDSO-G6, making it one of the smallest available footprints for a 42V-rated buck regulator. It is suitable for high-density PCB layouts.
Can the LM2842XMK-ADJL be used in automotive applications?
Yes. With its 42V maximum input rating and current-mode PWM control, the LM2842XMK-ADJL can handle automotive load-dump transients when combined with proper input filtering. It operates over the extended industrial temperature range, making it appropriate for in-vehicle power supplies and telematics modules.
