Device Overview

Summary

The MIC37100, MIC37101, and MIC37102 are 1A low dropout, linear voltage regulators that provide low-voltage, high-current output from an extremely small package. Utilizing proprietary Super βeta PNP® pass element, the MIC37100/01/02 offers extremely low dropout (typically 280mV at 1A) and low ground current (typically 11mA at 1A).

The MIC37100 is a fixed output regulator offered in the SOT-223 package. The MIC37101 and MIC37102 are fixed and adjustable regulators, respectively, in a thermally enhanced power 8-pin SOIC (small outline package) and the SOT-223 package. The MIC37102 is also available in the S-PAK power package for applications that require higher power dissipation or higher operating ambient temperatures.

The MIC37100/01/02 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V, or 2.5V to 1.8V or lower. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC37100/01/02 to provide 2.5V from a supply as low as 3V and 1.8V from a supply as low as 2.3V.

The MIC37100/01/02 is fully protected with overcurrent limiting and thermal shutdown. Fixed output voltages of 1.5V, 1.65V, 1.8V, 2.5V, and 3.3V are available on MIC37100/01 with adjustable output voltages to 1.24V on MIC37102.
