ACE ACE7805 3-termainal 1a positive voltage regulator Datasheet

ACE7805
3-Termainal 1A Positive Voltage Regulator
Description
The ACE7805 series of three terminal positive regulators are available in the TO-220 package and with
several fixed output voltages, making them useful in a wide range of applications.
Each type employs internal current limiting, thermal shut down 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 fixed
voltage regulators, these devices can be used with external components to obtain adjustable voltages
and currents.
