LX8630-00CP数据手册Microchip中文资料规格书

描述 Description

Key Features:
• Dropout Voltage Typically450mV at 3A and 50mV at10mA
• Low Quiescent Current,Typically Under 400µA,irrespective of Load
• Shutdown Current 10µA
• Adjustable Output Version in5-Pin TO-220 & TO-263Packages
• Low Reverse LeakageCurrent
• Short-Circuit and ThermalShutdown ProtectionThe LX8630 family are positive very low dropout regulators. They are designed to provide a power supply for very low headroom applications, such as 3.3V – 2.5V.BiCMOS technology allows an effective series pass element resistance, RDS(ON) of 150mOhm dropout voltage of 450mV at 3A.Low Quiescent Current and Logic Controlled Shutdown help conserve battery life and increase system efficiency. Typical quiescent current is under 400uA irrespective of load current, while the Shutdown current is only 10uA. The device will enter shutdown mode when the SHDN pin is pulled low.Thermal and Short Circuit Current Limiting: the LX8630 limits the current when the output is shorted, protecting the sensitive load circuits. The device will also turn off if the junction temperature exceeds 150°Available in Popular TO-220 and TO-263 Power Packages: adjustable versions have five leads, and fixed output voltage devices are supplied in three lead packages.
