This application note discusses the PNP voltage regulator. - High-Efficiency Reg has Low Drop-Out Voltage (Rev. B)PDF, 60 Kb, 修订版: B, 档案已发布: Apr 23, 2013
Conventional regulators have a high drop-out voltage that is a function of the total output current.However with just a regulator chip an external transistor and a few passive components this designforms a high output current regulator with a limited input voltage and high efficiency. The circuit presentedhas a drop-out of 0.7V at 5A load current and 1.3V at a current level of as high as
