General Description
The MIC39500 and MIC39501 is a 5A low-dropout linear voltage regulator that provides a low-voltage, high-current output with a minimum of external components. Utilizing Micrel’s proprietary Super βeta PNP™ pass element, the MIC39500 offers extremely low dropout (typically 400mV at 5A) and low ground current (typically 70mA at 5A).

FEATUREs
• 5A minimum guaranteed output current
• 500mV maximum dropout voltage over temperature
• 1% initial accuracy
• Low ground current
• Current limiting and thermal shutdown
• Reversed-battery and reversed-lead insertion protection
• Fast transient response
• TO-263 and TO-220 packages
• TTL/CMOS compatible enable pin (MIC39501 only)
• Error flag output (MIC39501 only)
