2A Low Dropout LDO
EM5102
General Description
Applications
EM5102 is a 2A 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 2A output current and ultra-low-drop
output voltage as well as full protection functions.
VOUT can be as low as 0.8V.

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.
θJA is measured in the natural convection at TA=25oC 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.
θJA PSOP-8 packages is 52°C /W on JEDEC 51-7 (4 layers,2S2P) thermal test board with 50mm2 copper area.
Devices are ESD sensitive. Handling precaution is recommended.
The device is not guaranteed to function outside its operating conditions.
Load regulation is measured by a current pulse with 50Hz frequency and 10% duty cycle.
The dropout voltage is defined as (VIN-VOUT), which is measured when VOUT equal to (VOUT,(NORMAL)-100mV).
