The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and 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 embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents

As a supplier of TIP122 transistors, we offer high quality and low cost products. Please let us know if you have any questions or if you would like to place an order.

The TIP122 is a darlington pair transistor that is used for high power switching applications. It is a three-terminal device that can be used as an amplifier, switch, or driver. The TIP122 is capable of handling up to 5 amps of continuous current and has a maximum voltage rating of 100 volts. It is commonly used in audio amplifiers, motor control circuits, and other high power applications.
