Description

General part information

BD42540FJ-C Series

The BD42540FJ-C is low quiescent regulator featuring 45V absolute maximum voltage, and output voltage tracking accuracy of ±10mV, 70mA output current and 40µA (typ.) current consumption. This tracker is therefore ideal for applications requiring a direct connection to the battery and a low current consumption. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, this IC also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.
