Product Overview

The LM2937IMP-12/NOPB is a Positive Voltage Regulator, capable of supplying up to 500mA of load current. The use of a PNP power transistor provides a low dropout voltage characteristic. With a load current of 500mA the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5V (1V ensured maximum over the full operating temperature range). Special circuitry has been incorporated to minimize the quiescent current to typically only 10mA with a full 500mA load current when the input to output voltage differential is greater than 3V. It requires an output bypass capacitor for stability. As with most low dropout regulators, the ESR of this capacitor remains a critical design parameter, but the LM2937 includes special compensation circuitry that relaxes ESR requirements. The device is stable for all ESR below 3Ω. This allows the use of low ESR chip capacitors.
  • Fully specified for operation over -40 to 125°C
  • Output current in excess of 500mA
  • Output trimmed for 5% tolerance under all operating conditions
  • Typical dropout voltage of 0.5V at full rated load current
  • Wide output capacitor ESR range up to 3Ω
  • Internal short-circuit and thermal overload protection
  • Reverse battery protection
  • 60V Input transient protection
  • Mirror image insertion protection
  • Green product and no Sb/Br

Applications

Automotive; Industrial; Automation & Process Control; Power Management
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
