LM340-N - 3-Terminal Positive Regulators

Description

The LM140/LM340A/LM340-N/LM78XXC monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible.

If adequate heat sinking is provided, they can deliver over 1.0A output current.

Features

  • 1.
  • 2 Complete Specifications at 1A Load.
  • Output Voltage Tolerances of ±2% at Tj = 25°C and ±4% Over the Temperature Range (LM340A).
  • Line Regulation of 0.01% of VOUT/V of ΔVIN at 1A Load (LM340A).
  • Load Regulation of 0.3% of VOUT/A (LM340A).
  • Internal Thermal Overload Protection.
  • Internal Short-circuit Current Limit.
  • Output Transistor Safe Area Protection.
  • P+ Product Enhancement Tested.
