EMP8110
1.5A Fixed Voltage LDO Linear Regulator
General Description
The EMP8110 is a CMOS low-dropout linear
regulator that operates in the input voltage range
from +2.5V to +6.5V and delivers 1.5A output
current.
The EMP8110 features include short-circuit
protection and thermal shutdown protection. The
EMP8110 series devices are available in both of
SOT-223 and TO-252 packages.
