Frequently Asked Questions
What is the dropout voltage of the LM2940SX-5.0/NOPB?
The LM2940SX-5.0/NOPB has a typical dropout voltage of 0.5V and a maximum of 1V. This means the input voltage only needs to exceed the 5.0V output by as little as 0.5V under typical conditions, making it ideal for battery-powered applications where maximizing usable battery capacity is critical.
What is the maximum input voltage for the LM2940SX-5.0/NOPB?
The LM2940SX-5.0/NOPB supports an operating input voltage range of 6.25V to 26V, with an absolute maximum rating of 60V. This wide input range makes it suitable for automotive and industrial environments where supply voltages can vary significantly or experience transient spikes.
What package does the LM2940SX-5.0/NOPB come in?
The LM2940SX-5.0/NOPB is available in a SOT-223 (JESD-30 code: R-PSSO-G3) surface-mount package. This compact 3-pin package provides excellent thermal dissipation due to its exposed metal tab, making it well suited for space-constrained PCB designs requiring up to 1A output current.
What are the typical applications for the LM2940SX-5.0/NOPB?
The LM2940SX-5.0/NOPB is commonly used in automotive electronics, battery-powered portable devices, embedded microcontroller power supplies, industrial sensors, and consumer electronics. Its low dropout characteristic and robust protection features (reverse battery, short-circuit, thermal shutdown) make it reliable across a wide range of 5V regulated power supply designs.
Is the LM2940SX-5.0/NOPB RoHS compliant?
Yes, the LM2940SX-5.0/NOPB is RoHS compliant with a Pb-free (lead-free) construction, as indicated by its JESD-609 code e3 and Pbfree Code: Yes. It meets modern environmental regulations for electronics manufacturing, making it suitable for use in products sold in the EU and other markets with strict environmental standards.
