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. Features Output Current up to 1A Output Voltages of 5V Thermal Overload Protection Short Circuit Protection Output Transistor Safe Operating Area Protection Absolute Maximum Ratings Parameter Symbol Max Input Voltage (Vo=5V to 18V) (Vo=24V) Vi Thermal Resistance Junction-Air RΘJA 65 Thermal Resistance Junction-Cases RΘJC 5 O C O C 35 40 Operating Temperature Range Topr 0~125 Storage Temperature Range Tstg -65~150 Unit V mA * When tested in free air condition, without heat sinking.
