70 mA Output Voltage Tracker
BD42540FJ-C
General Description
The BD42540FJ-C is low quiescent regulator featuring
45 V absolute maximum voltage, and output voltage
tracking accuracy of ±10 mV, 70 mA output current and
40 µA (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.

(Caution)
Exceeding the absolute maximum rating for supply voltage, operating temperature or other parameters can result in damages to or destruction
of the chip. In this event it also becomes impossible to determine the cause of the damage (e.g. short circuit, open circuit, etc.). Therefore, if any
special mode is being considered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such
as adding fuses, should be considered.
