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.

  • These are stress ratings only and functional operation of the device at these or any other conditions beyond those ind i- cated under “recommended operating conditions” is not implied.
  • On the adjustable version as shown in Fig.4, the V REF is available externally as 1.25V between VOUT and ADJ.
  • The voltage ratio formed by R1 and R2 should be set to conduct 10mA (min u- mum output load).
  • Its value is normally in the range of 100- 200Ω.
  • For example, with R1 = 124Ωand fRIPPLE = 120Hz, the CADJ should be 11μF.
  • COUT = 100μF or more is typical for high current regulator design.
  • Current protection is triggered at typically 1.6A.

Topics covered by the datasheet

The document includes sections related to:

  • Features
  • Applications
  • ORDERING INFORMATION
  • Electrical Characteristics
  • Application Information

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.
