ME6208
150 mA, high input voltage LDO Linear Regulators ME6208 Series
General Description
ME6208 series are low-dropout linear
voltage regulators with a built-in voltage
reference module, error correction module
and phase compensation module. ME6208
series are based on the CMOS process and
allow high voltage input with low quiescent
current. This series has the function of
internal feedback resistor setting from 3.0V
to 5.0V. The output accuracy is ± 2%.
Features
High output accuracy:± 2%
Input voltage:up to 18 V
Output voltage:3.0 V ~ 5.0V
Ultra-low quiescent current (Typ. = 3 µ A)
Output
Current:Iout = 200mA
(When
Vin = 7V and Vout =5V)
Importation good stability:Typ. 0.05% / V
Low temperature coefficient
Ceramic capacitor can be used
Typical Application
Electronic weighbridge
SCM
Phones, cordless phones
Security Products
Water meters, power meters

Precautions
During the test, if AC/DC power supply and the ceramic chip capacitors collocation is 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.
