PL7909XE3

The PL7909XE3 series of three-terminal negative regulators are available in the TO-220AB package. These PL7909XE3 regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each employs internal urrent limiting, thermal shutdown and safe operating area protection, making it essentially 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.
PL7909XE3 is characterized for operation from 0°C to +125°C, and if operating temperature is always high, please refer to the power dissipation curve.
