3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The H7808_I series of three-terminal positive regulators are
available in the TO-251 package and with several fixed output
voltages, making it useful in a wide range of applications. These regulators can provide local
on-card regulation, eliminating the distribution problems associated with single point regulation.
Each type employs internal current limiting, thermal shut-down and safe operating area
protection, making it essent-ially indestructible. If adequate heat sinking is provided, they can
deliver over 1A output current. Although designed primarily as fixed voltage regulators, these
devices can be used with external components to obtain adjustable voltages and currents.
H7808_I is characterized for operation from 0°C to +125°C, and if operating temperature will always hi, please refer the power dissipation curve.
