描述
由其分销商提供的 onsemi LM7808CT 的描述。
LM78XX Series 8 V Fixed Output 1 A 3-Terminal LDO Voltage Regulator - TO-220
Standard Regulator Pos 8V 2.2A 3-Pin(3+Tab) TO-220AB Rail
; Primary Input Voltage:35V; Output Voltage Fixed:8V; Dropout Voltage:2V; No. of Pins:3; Output Current:1A; Operating Temperature Range:-40°C to +125°C; Leaded Process Compatible:Yes; Output Current Max:1A; Output Voltage Max:8.3V ;RoHS Compliant: Yes
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.
