  • An Easy Solution to Current Limiting an Op Amp
    PDF, 35 Kb, Archivo publicado: oct 2, 2000
    Many circuits today not only require voltage regulation but they also need current regulation. Some systems draw excessive current during power on, which can cause expensive system components to burn up due to improper powering of supplies. This is not the only problem associated with excessive currents. Some applications need to limit the current an op amp can provide to a specific load. This cir
  • Packaging Limits Range of Linear Regulators
    PDF, 75 Kb, Archivo publicado: mayo 8, 2010
    The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential. This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.
