Measurement Circuit
Composite Regulator MM1448
Note 1: Output capacitance definitely is required to perform regulator and switch phase compensation. Also,
please note that oscillation may occur depending on the ESR value.
Note 2: Vo pin output noise voltage is reduced using NS pin capacitance value. Even if there is no need to
take output noise voltage into consideration, connection of a capacitor is recommended for stable
operation and improvement of AC characteristics.
Note 3: The cause of oscillation is due to set wiring and capacitance changes in capacitor caused by
temperatures changes, so please take extra care in placing the wires.
