Frequently Asked Questions
What is the output voltage and maximum output current of the LM2940T-10.0?
The LM2940T-10.0 provides a fixed 10V regulated output with a maximum output current of 1A. The dropout voltage is typically 0.5V and at most 1V at full load, so the input must be at least 11.5V to maintain regulation.
What is the input voltage range for the LM2940T-10.0?
The LM2940T-10.0 accepts input voltages from 11.5V minimum up to 26V maximum, with an absolute maximum rating of 60V. This makes it suitable for 12V and 24V automotive and industrial supply rails.
Does the LM2940T-10.0 offer any protection features?
Yes. The LM2940T-10.0 integrates reverse battery protection tolerating up to -60V, internal current limiting to prevent damage under overload conditions, and thermal shutdown that activates when the junction temperature becomes too high, ensuring robust operation in demanding environments.
What are common applications for the LM2940T-10.0?
Typical applications include automotive electronic control units, industrial sensors, embedded system power rails, and portable instruments that require a clean and stable 10V supply derived from a 12V or 24V source. The TO-220 package simplifies heatsinking for higher power dissipation.
Can I use the LM2940T-10.0 as a replacement for other LDO regulators?
The LM2940T-10.0 is pin-compatible with other TO-220 3-pin LDO regulators sharing the same fixed 10V output rating and can replace parts with similar specifications. Always verify the dropout voltage, input range, and protection features of the alternative before substituting in a design.
