ME6203
100 mA, High Input Voltage LDO Linear Regulators ME6203 Series
General Description
Features
ME6203 series are low-dropout linear
High output accuracy：± 2%
voltage regulators with a built-in voltage
Input voltage：up to 40 V
reference module, error correction module
Output voltage：1.8V ~ 12V
and phase compensation module. ME6203
Ultra-low quiescent current (Typ.= 3 µ A)
series are based on the CMOS process and
Output
Current：IOUT = 100mA
（When VIN = 5.5V and VOUT =3.3V）
allow high voltage input with low quiescent
current. This series can deliver 100mA
Short-circuit Current：(Typ.= 20mA)
output current and allow an input voltage as
Low temperature coefficient
high as 40V.This series has the function of
Ceramic capacitor can be used
internal feedback resistor setting from 1.8V
to 12V. The output accuracy is ± 2%.
Package
Typical Application
Electronic weighbridge
SCM
Phones, cordless phones
Security Products
Water meters, power meters
3-pin
SOT89-3 、SOT23-3 、TO92
Typical Application
Suggesting : The circuit uses the electrolytic capacitors
or tantalum capacitors in the best ,when it is applied in
the high input voltage.

Note ：
1. VOUT (T) ：Specified Output Voltage
2.VOUT (E) ：Effective Output Voltage ( ie. The output voltage when “VOUT (T)+ 2.0V”is provided at the VIN pin
while maintaining a certain IOUT value.)
3.VDIF：VIN1 –VOUT (E)’
V08

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)+2.2V} is input.
