Frequently Asked Questions
What output voltage range does the LM317LZ/NOPB provide?
The LM317LZ/NOPB provides an adjustable output voltage range from 1.25V to 37V, set by two external resistors connected between the output and adjust pins. This flexibility makes it suitable for generating a wide variety of supply voltages from a single regulator IC in custom power supply designs.
What is the maximum output current of the LM317LZ/NOPB?
The LM317LZ/NOPB is rated for a maximum output current of 100mA, placing it in the low-current linear regulator category. It is appropriate for powering op-amp stages, microcontroller auxiliary rails, small signal circuits, and sensor interfaces, but should not be used for loads exceeding 100mA without thermal derating consideration.
What package is the LM317LZ/NOPB available in?
The LM317LZ/NOPB is housed in a TO-92 through-hole package, a compact 3-pin plastic package commonly used for small transistors and low-power voltage regulators. The TO-92 package is ideal for breadboard prototyping, hand assembly, and low-cost PCB designs where through-hole mounting is preferred.
Is the LM317LZ/NOPB RoHS compliant?
Yes, the LM317LZ/NOPB suffix indicates it is a NOPB (No Lead) lead-free variant, making it RoHS compliant for use in commercial and consumer electronics products subject to EU RoHS and similar environmental regulations worldwide. Always verify the specific revision and packaging code when ordering for compliance-sensitive applications.
