Frequently Asked Questions
What is the LM2940IMP-9.0/NOPB and what does it do?
The LM2940IMP-9.0/NOPB is a 1A fixed 9V Low Dropout (LDO) linear voltage regulator from Texas Instruments. It regulates an input voltage of up to 26V down to a stable 9V output with only ~0.5V dropout at full load. The IMP suffix denotes the SOT-223 SMD package and the NOPB suffix confirms it is lead-free and RoHS compliant.
What package and pin count does the LM2940IMP-9.0/NOPB use?
It is housed in a SOT-223 package with 4 pins: pin 1 is the adjust/ground, pin 2 and the exposed tab is the output, and pin 3 is the input. The exposed metallic tab provides excellent thermal dissipation directly to the PCB, making it well-suited for compact, high-current designs.
What is the operating temperature range of the LM2940IMP-9.0/NOPB?
The LM2940IMP-9.0/NOPB is rated for industrial temperature operation from -40C to +125C, making it suitable for automotive accessories, outdoor equipment, and industrial control applications where wide temperature swings are expected.
What are suitable alternatives to the LM2940IMP-9.0/NOPB?
Functional pin-compatible or drop-in alternatives include the LM2940IMP-5.0/NOPB (5V version in same SOT-223 package), and the AP1117D90G-13 from Diodes Incorporated (9V, SOT-223, 1A). Always verify output voltage, dropout spec, and thermal ratings before substituting.
How do I buy the LM2940IMP-9.0/NOPB?
The LM2940IMP-9.0/NOPB is available from FindMyChip starting at $0.43 per unit at 100,000-piece quantity, or $1.54 each for single-unit orders. Minimum order quantity is 1 piece. Submit a quote request for bulk pricing, lead time confirmation, and global shipping options.
