3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The H78M24_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 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.
Description
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.
