L4949EP-E Datasheet

Low Dropout Regulators - LDO


The L4949EP-E ( L4949EP ) and L4949EP-E are monolithic integrated 5V voltage regulators with a very low dropout output and additional functions as poweron reset and input voltage sense. They are designed for supplying the microcomputer controlled systems especially in automotive applications. L4949EP-E Features •ECOPACK®: lead free and RoHS compliant•Automotive Grade: compliance with AEC guidelines•Operating DC supply voltage range 5 V - 28 V •Transient supply voltage up to 40V•Extremely low quiescent current in standby mode •High precision standby output voltage 5V±1%•Output current capability up to 100mA•Very low dropout voltage less than 0.5V•Reset circuit sensing the output voltage•Programmable reset pulse delay with external capacitor•Voltage sense comparator•Thermal shutdown and short circuit protections
