描述
由其分销商提供的 onsemi KA7812ERTM 的描述。
Standard Regulator Pos 12V 1A 3-Pin(2+Tab) DPAK T/R / IC REG LDO 12V 1A TO252-3
KA7812 Series 12 V Fixed Output 1 A SMT 3-Terminal LDO Regulator - TO-252
LINEAR VOLT REG, 1A, 12V, TO-252AB-3; Fixed Output Voltage Nom.: 12V; Adjustable Output Voltage Min: -; Adjustable Output Voltage Max: -; Input Voltage Min: 14.5V; Input Voltage Max: 27V; Product Range: 7812 Voltage Regulators
The KA78XXE/KA78XXAE series of three-terminal positive regulator are available in the TO-220/D-PAK 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.
