Linear regulator (Linear Regulator) for use in running a transistor or FET in its linear region, minus the excess voltage from the input voltage of the application, after adjustment of the output voltage. Its products are used in a small package, with excellent performance and provide value-added features such as thermal overload protection, current-limiting, shutdown mode can significantly reduce power consumption.
Linear regulator used in a transistor or FET operating in its linear region, minus the excess voltage from the input voltage of the application, after adjustment of the output voltage. So-called pressure drop in voltage, refers to the regulator output voltage necessary to maintain in its rating within 100mV of input voltage and output voltage is the minimum value of the difference. Positive output voltage LDO (low dropout) regulators usually use power transistors (also known as transmission equipment) as PNP. This allows saturation of the transistor, so regulators can have a very low voltage drop voltage, usually about 200mV; by contrast, using traditional linear regulator transistor NPN composite power supply voltage drop is about 2V. Negative-output LDO to use NPN pass as its equipment, its operating modes and output LDO PNP devices are similar.
