Frequently Asked Questions
What is the output voltage and current rating of the LM340T-15/NOPB?
The LM340T-15/NOPB provides a fixed 15V output with ±2% accuracy and a maximum continuous output current of 2.4A, making it suitable for powering analog circuits and motor driver stages that require a stable 15V rail.
What input voltage range does the LM340T-15/NOPB support?
The device accepts an input voltage from 17.5V minimum up to 35V absolute maximum. The typical dropout voltage is 2V, so a supply of at least 17V is needed to maintain regulation at the 15V output.
What are common applications for the LM340T-15/NOPB?
Typical applications include industrial power supplies, audio amplifier bias rails, op-amp dual-supply circuits, sensor interface modules, and consumer electronics requiring a regulated 15V, 2.4A supply. The TO-220 package allows easy heatsinking for higher-power use cases.
Is the LM340T-15/NOPB RoHS compliant and what does NOPB mean?
Yes, the NOPB suffix indicates the part is lead-free (No Lead, Pb-free) and meets the JESD-609 e3 environmental standard, making it fully RoHS compliant for use in modern eco-friendly product designs.
What package does the LM340T-15/NOPB use and are there pin-compatible alternatives?
The LM340T-15/NOPB comes in a 3-pin TO-220 (R-PSFM-T3) through-hole package. It is pin-compatible with other LM7815-series regulators such as the LM7815CT and UA7815, allowing direct substitution in most circuit designs.
