Notas de aplicación

  • Technical Review of Low Dropout Voltage Regulator Operation And Performance
    PDF, 284 Kb, Archivo publicado: agosto 30, 1999
    This application report provides a technical review of low dropout (LDO) voltage regulators and describes fundamental concepts including dropout voltage quiescent current and topologies. The report also includes detailed discussions of load/line regulation efficiency frequency response range of stable ESR and accuracy of LDO voltage regulators.
  • Fundamental Theory of PMOS LDO Voltage Regulators
    PDF, 66 Kb, Archivo publicado: mayo 7, 1999
    This report presents a fundamental understanding on the theory of low-dropout voltage regulators using a PMOS FET as the pass element to adjust the output current to the load requirements.
