ME6118
1A High Speed LDO Regulators ME6118 Series
General Description
Features
The ME6118 series are highly accurate, low noise,
Output Current in Excess of 1A
LDO Voltage Regulators that are capable of providing
Dropout Voltage:80mV@ IOUT =100mA
(ME6118A33)
an output current that is in excess of 1A with a
maximum dropout voltage of 1.3V at 1A ( ME6118
Operating Voltage Range:

Note :
1. VOUT (T) :Specified Output Voltage
2.VOUT (E) :Effective Output Voltage ( ie. The output voltage when “VOUT (T)+1.2V”is provided at the Vin pin while
maintaining a certain Iout value.)
3.VDIF:VIN1 –VOUT (E)’
VIN1 :The input voltage when VOUT(E)’ appears as input voltage is gradually decreased.
VOUT (E)’=A voltage equal to 98% of the output voltage whenever an amply stabilized Iout and {VOUT
(T)+1.2V} is input.

Applications Information
1. Input Bypass Capacitor
An input capacitor is recommended. A 10uF tantalum on the input is a suitable input bypassing for almost all
applications.
2. Output Capacitor
The output capacitor is critical in maintaining regulator stability, and must meet the required conditions for both
minimum amount of capacitance and ESR (Equivalent Series Resistance).The minimum output capacitance
required by the ME6118 is 10µF,if a tantalum capacitor is used. Any increase of the output capacitance will
merely improve the loop stability and transient response. The ESR of the output capacitor should be less than
0.5Ω .
3. Load Regulation
The ME6118 regulates the voltage that appears between its output and ground pins. In some cases, line
resistances can introduce errors to the voltage across the load. To obtain the best load regulation, a few
precautions are needed. Figure1, shows a typical application using a fixed output regulator. The Rt1 and Rt2 are
the line resistances. It is obvious that the VLOAD is less than the VOUT by the sum of the voltage drops along the
line resistances. In this case, the load regulation seen at the R LOAD would be degraded from the datasheet
specification. To improve this , the load should be tied directly to the output terminal on the positive side and
directly tied to the ground terminal on the negative side.
