ME6209A33PG
Low Power Consumption LDO ME6209 Series
General Description
The ME6209 series are a group of positive voltage
output, three –pin regulator, that provide a high
current even when the input/output Voltage
differential is small. Low power consumption and
high accuracy is achieved through CMOS
technology. They allow input voltages as high as
18V.
Features
Ultra low quiescent current: 3.0uA(typ)
High input voltage (up to 18V)
Low dropout voltage :80mV@Iout=40mA
（VOUT=3.3V）
Output voltage accuracy： ±2％
Maximum output current：250mA
（within max.power dissipation,VOUT =3.3V）
Low temperature coefficient
Package：SOT23-3、TO-92、SOT-89-3
Typical Application
Cameras, video recorders
Voltage regulator for microprocessor
Voltage regulator for LAN cards
Wireless communication equipment
Audio/Video equipment
Precautions
During the test, if AC/DC power supply and the ceramic chip capacitors collocation are used, there may be
serious voltage spike phenomenon instantaneously. When the power supply access to 16V, the voltage is
rushed to about 30V instantaneously. Because of exceeding the limit voltage of chip, the chip is damaged. If
you string a small resistance of 1 ohm in the input end during the test, the peak phenomenon can be
avoided.
In the test, there is serious burr phenomenon only when the AC/DC power is used with ceramic chip
capacitors. But electrolytic capacitors and tantalum capacitance won't appear above phenomenon. Please
be sure to pay attention to this point when you use AC/DC power.
In normal use, when any type of capacitor is used with battery or the supply of fire power, the above
phenomenon doesn’t occur.
