General Description

The BDL00A5NUF-C and BDL00A5EFJ-C is a linear

regulator designed as a low current consumption product

for power supplies in various automotive applications.

This product is designed for up to 20 V as an absolute

maximum voltage and to operate until 500 mA for the

output current with low current consumption 30 μA (Typ).

The reference voltage accuracy (ADJ pin voltage

accuracy) is a very high accuracy (Note 1), ±2 . The output

voltage can be adjusted between 1 V and 17 V by an

external resistive divider connected to the ADJ pin.

The output shutdown function is integrated in the devices.

A logical “HIGH” at the EN Pin turns on the device, and in

the other side, the device is controlled to disable by a

logical “LOW” input to the EN Pin.

The device features the integrated Over Current Protection

to protect the device from a damage caused by a shortcircuiting

or an overload. This product also integrates

Thermal Shutdown Protection to avoid the damage by

overheating.

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

(Note 1) The tolerance of feedback resistor is not included.
