Product Summary

The LM7812CT 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 external components to obtain adjustable voltages and currents.

Parametrics

LM7812CT absolute maximum ratings: (1)Input Voltage, VO = 5V to 18V: 35 V; (2)Thermal Resistance Junction-Cases (TO-220): 5 °C/W; (3)Storage Temperature Range: -65 to +150°C; (4)Output Voltage: 4.8 to 5.2 V; (5)Quiescent Current: 5.0 to 8.0 mA.

Features

LM7812CT features: (1)Output Current up to 1A ; (2)Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24; (3)Thermal Overload Protection ; (4)Short Circuit Protection; (5)Output Transistor Safe Operating Area Protection.
