H7812AI H7812BI
3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The H7812_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. H7812_I is characterized for operation from 0C to +125C, and if operating temperature will always hi, please refer the power dissipation curve.
