General Description

BD4271xxx-C Series are automotive voltage regulators with watchdog timer and offers the output current of 550 mA while limiting the quiescent current low.

A logical “HIGH” at the CTL pin enables the LDO regulator and “LOW” disables the LDO regulator and keeps current consumption low.

A reset signal is generated for an output voltage VO of Typ 4.65 V.
