Today, we will introduce the SL4949 Linear Voltage Regulators (LDO).

Description

SL4949 is a low voltage drop LDO voltage regulator with the output voltage of 5V, integrated with the power on reset function and the input voltage monitoring function in the chip. SL4949 can provide stable supply voltage for the control system of micro-processors,with typical output current as high as 100mA and transient input voltage of 42V,and is very suitable for applications in working environment of automotive electronics. Supporting Reset output,it can be applied to logic control of micro-processors,in addition, it supports Sense monitoring,and can output the waming signal before the output of the reset signal.Reasonable use ofthe Sense monitoring function can make micro-processors conduct necessary treatment measures before the stop of micro-processors with Reset.
