14.16.LM7808

14.16.1.Description

The L7800 series of three-terminal positive regulators is available in TO -220 TO -220FP TO-3 and D 2
PAK 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 employs internal current limiting, thermal shutdown and safe
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.

14.16. 2.Features

Output Current Up To 1.5 A
Output Voltages of 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V
Thermal Over load protection
Short Circuit Protection
Output Transition SOA Protection

14.17.BDX53BFI

14.17.1.Description
The BDX53BFI is silicon epitaxial-base NPN power transistor in monolithic Darlington configuration and
are mounted in ISOWATT220 plastic package. It is intended for use in hammer drivers, audio amplifiers
and other medium power linear and switching applications. The complementary PNP type is t h e
BDX54BFI.
