MC78M05 Fairchild Semiconductor, MC78M05 Datasheet - Page 3

• Manufacturer Part Number: MC78M05
• Description: The MC78MXX/LM78MXX series of three-terminal positive regulators are available in the TO-220/D-PAK package with several fixed output voltages making it useful in a wide range of applications
• Manufacturer: Fairchild Semiconductor

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.
