Applications

  • Standard 3-Lead Transistor Package
  • Eliminates Stocking Many Fixed Voltages ABSOLUTE MAXIMUM RATINGS Input - Output Voltage Differential 40 V Operating Junction Temperature Range -40°C to +125°C from power supply filter. **Co is not needed for stability, however, it does improve transient response. Vout = 1.25 V (1+R2/R1) + IAdjR2 Since I Adj is controlled to less than 100µA, the e rror associated with this term is negligible in most applications.
