• Manufacturer Part Number: MC78M08
• Description: 3-Terminal 0.5A Positive Voltage Regulator
• Manufacturer: Fairchild

Typical Applications
Notes:
1. To specify an output voltage, substitute voltage value for "XX"
2. Although no output capacitor is needed for stability, it does improve transient response.
