MIC39300/39301 Micrel MIC39300/39301 3A Low-Voltage Low-Dropout Regulator General Description The MIC39300 and MIC39301 are 3.0A low-dropout linear voltage regulators that provide a low voltage, high-current output with a minimum of external components. Utilizing Micrel’s proprietary Super βeta PNP™ pass element, the MIC39300/1 offers extremely low dropout (typically 400mV at 3.0A) and low ground current (typically 36mA at 3.0A). The MIC39300/1 is ideal for PC add-in cards that need to convert from standard 5V or 3.3V down to new, lower core voltages. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC39300/1 to provide 2.5V from a supply as low as 3V. The MIC39300/1 also has fast transient response for heavy switching applications.
