Frequently Asked Questions
What is the output voltage and current rating of LM2940IMPX-8.0/NOPB?
The LM2940IMPX-8.0/NOPB provides a fixed 8V output voltage with up to 1A continuous output current. The dropout voltage is typically 0.5V, meaning the input supply needs to be at least 8.5V for proper regulation.
What package and pin count does LM2940IMPX-8.0/NOPB use?
It comes in a 4-pin SOT-223 surface-mount package. The SOT-223 offers excellent thermal performance due to its large exposed tab, making it suitable for high-current LDO applications on compact PCBs.
What is the operating temperature range of LM2940IMPX-8.0/NOPB?
The 'I' grade in the part number denotes industrial temperature range: –40°C to +125°C. This makes it suitable for automotive, industrial, and outdoor applications that experience wide thermal variations.
Is LM2940IMPX-8.0/NOPB RoHS compliant and lead-free?
Yes. The '/NOPB' suffix explicitly indicates a lead-free, RoHS-compliant version. It uses a tin-based finish instead of tin-lead, meeting EU RoHS Directive and WEEE requirements.
What are good alternatives to LM2940IMPX-8.0/NOPB?
Pin-compatible or functionally equivalent alternatives include the ON Semiconductor NCP4624 (adjustable, SOT-223), Diodes Inc. AZ1117IH-8.0TRG1 (8V LDO, SOT-223), and Microchip MCP1826-8002E/DC (8V, 1A LDO). Always verify pinout and electrical specs before substituting.
