Page No. : 1/12
General Description
EM5103 is a 3A low dropout linear regulator designed for low dropout and high current applications. This device
works with dual supplies, a control input for the control circuitry and a power input as low as 1.2V for providing
current to output.
It features 3A output current and ultra-low-drop output voltage as well as full protection functions.
VOUT can be as low as 0.8V.
Features
●VIN Range 1.2V to 5.5V
●VOUT is Adjustable (0.8V Min)
●Excellent Line Regulation
●Excellent Load Regulation
●3A Guaranteed Output Current*
*Check thermal design information.
●300mV @ 3A Dropout Voltage
●OTP and OCP Functions
●Very Low On-Resistance
●Enable & Power good Signal
Applications
●Notebook & Netbook
●Graphic Cards & MB
●Low Voltage Logic Supplies
●Chipset Supplies
●Server System
●SMPS Post Regulators
