ME6118
1A Adjustable Voltage High Speed LDO Regulators ME6118 Series
General Description
The ME6118 series are highly accurate, low noise,
LDO Voltage Regulators that are capable of
providing an output current that is in excess of 1A
with a maximum dropout voltage of 1.3V at 1A
（ME6118A33）.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.
