BD4271FP2-C - 550mA Output LDO Regulator

Download the BD4271FP2-C datasheet PDF. This datasheet also covers the BD4271HFP-C variant, as both devices belong to the same 550ma output ldo regulator family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • Low ESR ceramic capacitors applicable for output.
  • Low drop voltage: PDMOS output transistor.
  • Power on and under-voltage reset.
  • Programmable reset delay and watchdog time by external capacitor Key Specifications.
  • AEC-Q100 qualified (Note 1).
  • Qualified for Automotive.

Datasheet LDO Regulators with Watchdog Timer and Voltage Detector 550 mA Output LDO Regulator with WDT and Voltage Detector BD4271xxx-C Series 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. The reset delay time and watchdog time (WDT) can be programmed by the external capacitor.
