Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- This device is supplied in a 16-lead surface-mount plastic SOIC with exposed pad to provide a low-resistance path for maximum power dissipation, low junction temperature, and improved reliability. ■Wide 8 V to 50 V Input Range ■Adjustable.
- Under any set of conditions, do not exceed a junction temperature of +125°C.
- Recommended Operating Conditions Min Max Units DC Input Voltage* V DC Output Current 0.02 A Adjustable Voltage Range 1.2 V Operating Junction Temp. -30 +125 °C† *The minimum value of dc input voltage is 8 V when the output is less than 5 V.
- The recommended maximum value is 50 V when the output value is more than 2.5 V, derated linearly to 30 V when the output is 1 V. †For the availability of parts meeting -40°C require- ments, contact Allegro’s Sales Representative.

Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
