The SP78XX series are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. This series of regulators are complete with internal current limiting, thermal shutdown protection, and safe-area compensation which make them virtually immune from output overload. If adequate heat sinking are provided, these regulators can deliver output currents up to 1.0A. The SP78XX series are available in two standard plastic packages: TO-220 and TO-252.

Features:

Output Current up to 1.0A

Fixed Output Voltages of 5 V and 12V

Output Voltage Tolerances of ±5% over the Full Temperature Range

Internal Short Circuit Current-limiting

Internal Thermal Overload Protection

Available in Lead Free, RoHS Compliant Packages
