Bare Die Data Sheet: LM120K-5

LM120K-5 3-terminal fixed -5V negative regulator supplies >= 1.5A of current & requires only x1 external compensation capacitor at the output. Overload immunity features include internal current limiting, safe-area compensation + thermal shutdown.
This device suits hybrid & MCM designers needing high reliability with fixed 5V negative voltage regulation. This bare die replaces National (NSC) or Texas Instruments (TI) LM120K-5, LM320K-5, LM120KG-5 and LM120KG-5 MD8.
  • 4% voltage output tolerance over full temperature range
  • Wide input voltage range
  • Internal Short-Circuit Current Limiting
  • Internal Thermal Overload Protection
  • No external components required
  • Military Temperature Range for High Reliability
  • Provides Point-of-Source regulation with lower noise
  • x2 magnitude impedance improvement with lower bias current and noise when replacing Zener diode/resistor combinations
  • Can be used with power-pass elements to make high-current voltage regulators
  • Positive Voltage complement is LM140K-5
