For Automotive 45 V Input
50 mA Fixed Output LDO Regulators
BD7xxL05G-C Series
General Description
The BD7xxL05G-C linear regulators are designed
as low current consumption products for power
supplies in various automotive applications.
These products are designed for up to 45 V
absolute maximum supply voltage and operate until
50 mA output current with low current consumption
of 6 μA (Typ). It can regulate the output at a very
high accuracy of ±2 %.
This device features an integrated Over Current
Protection to keep the device from a damage that is
caused by short-circuit or overload. This product
also integrates a Thermal Shutdown protection to
avoid the damage from overheating.
Furthermore, low ESR ceramic capacitors are
sufficiently applicable for the output phase
compensation.
