Low Quiescent Current Low Dropout
MD71XXH Series
High Input（30V）CMOS Voltage Regulator
30mA
The MD71XXH series is a family of Low Dropout Positive regulators.which developed by using
CMOS technology. These IC products perform with high output voltage accuracy, low quiescent
current , Low Input-Output Dropout as built-in low on-resistance.At the same time with high input
voltage capacity it can be up to 30V, suitable for applications which requires higher voltage
circuit.

■Standard Circuit:
Note: The above connection diagram and constant will not guarantee successful
operation.Perform through evaluation using the actual application to set the constant.
■using conditions:
Input capacitors(CIN): >1.0 µF.
Output capacitors(CL): >2.2 µF(tantalum capacitors).
*1. CIN is a capacitor for stabilizing the input.
*2. A ceramic capacitor can be used for CL besides a tantalum capacitor.
* Note: In general, linear regulated power supply may lead to oscillation by choosing the
different external components. Please make sure the capacitor before used in the application
circuit does not oscillate.
■Technical Terms
1. Output capacitors (CL)
Output capacitors are generally used to stabilize regulation operation and to improve
transient response characteristics. But the MD71XXH series can provide stable operation
without output capacitors. Capacitors are used only to improve transient response
characteristics. Output capacitors can hence be removed in applications in which
transient response can be negligible. When an output capacitor is used, a low ESR
(Equivalent Series Resistance) capacitor like ceramic capacitor can also be used.
