H7809AI H7809BI

3-TERMINAL POSITIVE VOLTAGE REGULATOR

Description

The H7809_I series of thr ee-ter minal positi ve reg ulators are av ailable in the TO-251 package and w ith several fix ed 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 essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primari ly as fixed voltage regulators , these devices can be used with external components to obtain adjustable v olt ag es and cur rents. H7809_I is characterized for operation from 0°C to +125°C, and if operating temperature will always hi, please refer the power dissipation curve.
