Microminiature Low-Power Consumption Low-Saturation Regulator
Monolithic IC MM1385
Outline
This IC is a microminiature stabilized power supply device featuring an output voltage precision of within ±±2
and output currents of up to ±00mA; the input/output voltage difference at 50mA is only 0.1V.
This chip is provided with an output noise reduction pin and output on/off control pin, and is ideal for use in
portable equipment.
