Features

make BL8530C series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries. BL8530C has a drive pin (EXT) for external transistor. So it is possible to load a large output current with a power transistor which has a low saturation voltage. BL8530C integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. BL8530C is available in SOT-23-3 and SOT-23-5 packages which are PB free. And in SOT-23-5 the device can be switch on or off easily by CE pin, to minimi.
