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

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA=25°C on a 4-layers high effective thermal conductivity test board with
minimum copper area of JEDEC 51-7 thermal measurement standard. The case point of θJC is on the expose pad for
PSOP-8 package.
Note 3. θJA is 52°C/W for PSOP-8 packages on JEDEC 51-7 (4 layers,2S2P) thermal test board with 50mm² copper area.
Note 4. Devices are ESD sensitive. Handling precaution is recommended.
Note 5. The device is not guaranteed to function outside its operating conditions.
Note 6. Load regulation is measured by a current pulse with 50Hz frequency and 10% duty cycle.
Note 7. The dropout voltage is defined as (VIN-VOUT), which is measured when VOUT equal to (VOUT,(NORMAL)-100mV).
