Voltage Tracker
250 mA Output Voltage Tracker
BD42530xxx-C Series
General Description
The BD42530xxx-C Series are low quiescent voltage
trackers featuring 45 V absolute maximum voltage, and
output voltage tracking accuracy of ±10 mV, 250 mA
output current and 40 µA (Typ) current consumption.
These trackers are 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, these ICs 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.
