ME6118
800mA Adjustable Voltage High Speed LDO Regulators ME6118 Series
General Description
Features
The ME6118 series are highly accurate, low noise,
LDO Voltage Regulators that are capable of
providing an output current that is in excess of
800mA with a maximum dropout voltage of 1.0V at
800mA（ME6118A18）.This series contains four
fixed output voltages of 1.2V,1.8V,2.5V and 3.3V
that have no minimum load requirement to
maintain regulation. On chip trimming adjusts the
reference/output voltage to within ±2% accuracy.
Internal protection features consist of output
current limiting, safe operating area compensation,
and thermal shutdown. The ME6118series can
operate with up to 18V input. Devices are available
in SOT223.
