The exact range depends on the resistor value and operating temperature."},{"question":"Can LM334 be used as a constant current source?","answer":"Yes. The LM334 is designed as a three-terminal current source. With one external resistor, it delivers a constant current that is proportional to absolute temperature (PTAT), making it suitable for bias, LED drive, and sensor excitation."},{"question":"What is the difference between LM334MX/NOPB and LM334Z?","answer":"The LM334MX/NOPB is the surface-mount 8-SOIC variant, while the LM334Z is the through-hole TO-92 version. Electrical specifications are identical; the choice is dictated by board assembly process and thermal dissipation needs."},{"question":"How to set current with LM334MX/NOPB?","answer":"Connect a resistor (R_SET) between the R and V− pins. The output current I_SET ≈ (67.7 mV × T) / R_SET, where T is in Kelvin. At 25°C, a 1 kΩ resistor sets roughly 227 µA. The ±6% accuracy covers initial tolerance and drift."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM334MX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM334MX-NOPB when reusing this data.
