LM78XX Series 12 V Fixed Output 1 A 3-Terminal LDO Voltage Regulator - TO-220
ON SEMICONDUCTOR - LM7812CT - LINEAR VOLTAGE REGULATOR, 12V, TO-220-3
Standard Regulator Pos 12V 2.2A 3-Pin(3+Tab) TO-220AB Rail
Standard Regulator Neg -1.2V to -37V 1.5A 3-Pin(3+Tab) TO-220 Tube
The LM78XX 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.
