H78M12BT

The H78M12_T series of three-terminal positive regulators are available in the TO-126 package. This regulator can provide local on-card regulation,eliminating the distribution problems associated with single point regulation. Each H78M12_T series  device employs internal current limiting, thermal shut-down and safe operating area protection, making it essentially indestructible.If adequate heat sinking is provided, they can deliver over 0.5A output current. Although designed primarily as fixed voltage regulators, this device can be used with external components to obtain adjustable voltages and currents.

• Output current up to 500mA is available.
• Eliminates external compensating circuit.
• Built-in current limiter prevents elements from destruction when load is short circuit.
• Built-in chip junction temperature limiting circuit protects elements against thermal destruction.
• Built-in internal power dissipation limiting circuit protects transistors at output driver.
