General Description
The Micrel MIC37300/01/02/03 is a 3.0A low-dropout linear voltage regulator that provides a low-voltage, high-current output with a minimum number of external components. It offers high precision, ultra-low-dropout (500mV overtemperature), and low-ground current.

Features
• 3.0A minimum guaranteed output current
• 500mV maximum dropout-voltage overtemperature
    – Ideal for 3.0V to 2.5V conversion
    – Ideal for 2.5V to 1.8V, 1.65V, or 1.5V conversion
• Stable with ceramic or tantalum capacitor
• Wide input voltage range
    – VIN: 2.25V to 6.0V
• +1.0% initial output tolerance
• Fixed and adjustable output voltages:
    – MIC37300—3-pin fixed voltages
    – MIC37301—5-pin S-Pak or 8-pin e-Pad SOIC fixed voltages with flag
    – MIC37302—5-pin adjustable voltage
    – MIC37303—8-pin e-Pad SOIC adjustable
    voltage with flag
