Frequently Asked Questions

What is the dropout voltage of the LM2931Z-5.0/NOPB?

The LM2931Z-5.0/NOPB has a typical dropout voltage of 0.3V and a maximum of 0.6V at full load current. This low dropout characteristic allows the device to regulate a stable 5V output even when the input supply is only 5.6V, making it suitable for battery-powered and automotive applications.

What is the input voltage range for the LM2931Z-5.0/NOPB?

The LM2931Z-5.0/NOPB operates with an input voltage range from 6V minimum to 26V maximum absolute maximum. This wide range supports automotive 12V/24V rails and general industrial power supplies, providing flexibility across many circuit designs.

What package does the LM2931Z-5.0/NOPB come in and is it RoHS compliant?

The LM2931Z-5.0/NOPB is available in a TO-92 (transistor outline, vertical) through-hole package with 3 leads, denoted by JESD-30 code O-PBCY-W3. The '/NOPB' suffix indicates it is lead-free and RoHS compliant per JESD-609 code e3, making it suitable for environmentally regulated designs.

Can the LM2931Z-5.0/NOPB be used as a replacement for other 5V LDO regulators?

Yes, the LM2931Z-5.0/NOPB is pin-compatible with many standard 3-pin TO-92 LDO regulators offering 5V fixed output. It can replace parts with similar voltage, current, and package specifications. Always verify dropout voltage, input range, and quiescent current requirements match your circuit before substituting.
