Frequently Asked Questions
What is the output voltage range of the LM350K STEEL/NOPB?
The LM350K STEEL/NOPB provides an adjustable output voltage from 1.2V to 33V. Output voltage is set by a resistor divider network connected to the ADJ pin, allowing precise regulation across the full range with less than 0.1% load regulation typical.
What package does the LM350K STEEL/NOPB use and what are the thermal benefits?
The LM350K uses a TO-3 metal package, which offers very low thermal resistance (junction-to-case ~3C/W). This makes it ideal for high-current applications up to 3A where heat dissipation is critical, particularly in industrial and lab power supply designs.
What are suitable alternatives or replacements for the LM350K STEEL/NOPB?
Compatible alternatives include the LM317K (1.5A, same TO-3 package), LM338K (5A adjustable), and LM196K (10A, TO-3). For lower current needs, LM317HVK or LM317T in TO-220 can substitute. All share the same 1.2V to 33V adjustable output architecture.
Is the LM350K STEEL/NOPB RoHS compliant and lead-free?
Yes. The NOPB suffix confirms this device is lead-free (No Lead) and RoHS compliant. It meets EU RoHS Directive 2011/65/EU restrictions on hazardous substances, making it suitable for all consumer, industrial, and export applications requiring green compliance.
What is the minimum order quantity and typical lead time for LM350K STEEL/NOPB?
The minimum order quantity (MOQ) is 10 units. Pricing starts at $88.57 for 10 units and scales to $59.95 at 10,000 units. The part is in active production at Texas Instruments and typically ships within standard lead times. Contact us for volume quotes.
