EC49513A/L  
300mA Linear Regulator with Enable  
And Fast Discharge Function  
Dropout Voltage  
A regulator’s minimum input output voltage differential, or dropout voltage, determines the lowest usable  
supply voltage. In battery powered systems, this will determine the useful end of life battery voltage. The  
EC49513A/L uses a P-channel MOSFET pass transistor, its dropout voltage is a function of drain-to-source  
on-resistance (RDS (ON)) multiplied by the load current.  
VDROPOUT = VIN VOUT = RDS (ON ) xIout
