Low-Noise, Low-Satulation Three-Pin Regulator
Monolithic IC MM1180, 1181
Outline
MM1180 series is high withstand voltage, low noise stabilized power supply with reduced reactive current at
low input voltage and small input / output differential voltage 0.2V at 40mA output current. The output current
is up to 100mA. MMP-4P package can control output ON / OFF by ON / OFF terminal.
