3- Terminal Positive Voltage Regulators
7805AJ Pin Assignment
3-Lead Plastic TO-252
Package Code: J
Pin 1: VIN
Pin 2 & Tab: GND
Pin 3: VOUT

Description
The 7805A can provide local on-card regulation, eliminating the
distribution problems associated with single point regulation. Each employs
internal current limiting, thermal shut-down and safe operating area protection,
making it essen-tially 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.
