General Description
The ML6206S series are highly precise, low power
consumption, high voltage, positive voltage output,
three-pin regulator. It provides high output current
even when the input/output voltage differential is
small.
The ML6206S consists of a high-precision voltage
reference, an error correction circuit and reverse
battery protection.

Note on Use
1. Oscillation may occur as a result of the impedance present between the power supply and the IC’s input. Please use a
capacitor (CIN) of at least 1uF, when the impedance is 10 ohm or more.
With a large output current, Voltage output can be stabilised by increasing capacitor (CIN) size. If CIN is small and
capacitor (CL) size is increased, oscillation may occur. In such cases, Voltage output can be stabilised by either increasing
the size of CIN or decreasing the size of CL.
2. Please ensure that output current (IOUT) is less than Pd / (VIN-VOUT) and does not exceed the stipulated Continuous Total
Power Dissipation value (Pd).

Note : 1. VOUT(T) = Specified Output Voltage.
2. VOUT(E) = Effective Output Voltage (i.e. the output voltage when (VOUT(T)+1.0V) is provided at the VIN pin
while maintaining a certain IOUT value).
3. Vdif = VIN1(Note 4) – VOUT(E)
4. VIN1 = The input voltage at the time 98% of VOUT (E) is output (input voltage has been gradually reduced).
