Fonctionnalités et applications

The MIC39300-1.8WU is a 3.0 A low-dropout linear voltage regulator that provide a low voltage, high-current output with a minimum of external components. Utilizing Micrel?s proprietary Super ?eta PNP? pass element, the MIC39300/1/2 offers extremely low dropout (typically 385 mV at 3.0 A) and low ground current (typically 36 mA at 3.0 A).

The MIC39300-1.8WU is ideal for PC add-in cards that need to convert from standard 3.3 V to 2.5 V or 2.5 V to 1.8 V. A guaranteed maximum dropout voltage of 500 mV over all operating conditions allows the MIC39300/1/2 to provide 2.5 V from a supply as low as 3 V, and 1.8 V from a supply as low as 2.5 V. The MIC39300/1/2 also has fast transient response for heavy switching applications. The device requires only 47?F of output capacitance to maintain stability and achieve fast transient response. The MIC39300-1.8WU fully protected with over current limiting, thermal shutdown, reversed-battery protection, reversed-leakage protection, and reversed-lead insertion.

Key Features :

  • 3.0 A minimum guaranteed output current
