µPC2900 Series

CAUTION ON USE

When using the

µPC2900 series at the input voltage which is lower than in the recommended operating condition,

the big quiescent current flows through devices because the transistor of the output paragraph is saturated (Refer

µPC2900 series have saturation protection

circuits, but they sometimes need about 80 mA current. Therefore the power supply on the input needs the enough

current capacity to pass this quiescent current when the devices startup.
