LM140K-12 General Description

To ensure easy usage, the LM140K series regulators are designed to minimize the need for external components. However, bypassing the output does improve transient response, while input bypassing is necessary only if the regulator is located far from the filter capacitor of the power supply

Key Features

  • Complete Specifications at 1A Load
  • Output Voltage Tolerances of ±4% at Tj = 25°C
  • Internal Thermal Overload Protection
  • Internal Short-circuit Current Limit
  • Output Transistor Safe Area Protection
  • P+ Product Enhancement Tested
