Frequently Asked Questions
What is the output voltage range of the LM337KVURG3?
The LM337KVURG3 provides an adjustable negative output voltage from -1.2V to -37V, set by two external resistors connected to the ADJ pin. This makes it suitable for a wide range of negative rail applications from low-voltage analog references to higher-voltage power supplies.
What package does the LM337KVURG3 use and how many pins does it have?
The LM337KVURG3 uses a TO-220-3 through-hole package with 3 pins: Input, Output, and Adjust. The metal tab is electrically connected to the Output pin and can be bolted to a heatsink to dissipate significant power with adequate thermal management.
What are common alternatives for the LM337KVURG3?
Direct pin-compatible alternatives include the LM337T (commercial temperature range), LM337HVT (extended input voltage up to 47V), and the LM337IMP (smaller SOT-223 package). The LT337A from Analog Devices and ON Semiconductor LM337 are also functionally equivalent drop-in replacements.
Is the LM337KVURG3 RoHS compliant?
Yes, the LM337KVURG3 is RoHS compliant and lead-free. The UR suffix in the part number indicates it meets the Green/RoHS requirements per Texas Instruments standard packaging classification.
What applications is the LM337KVURG3 best suited for?
The LM337KVURG3 is ideal for adjustable negative power supplies, dual-tracking regulators paired with LM317, op-amp bipolar supply rails, battery charging circuits, and industrial control equipment requiring a stable regulated negative voltage over a -40 to +125 degree C operating range.
