BD4xx and BD7xx Series Regulators

ROHM Semiconductor offers two new series of low quiescent linear regulators for automotive applications

Image of ROHM BD4xx and BD7xx Series RegulatorsROHM's new low quiescent (lq) current regulators feature a rated voltage of 50 V, 200/500 mA output current and an output voltage accuracy of ±2%. In order to provide the best solution for each application, ROHM offers two new series of products:

-The BD4xx series offers compatible devices with a good selection of standard packages and a low Iq of 40 µA (Typ.)

-The BD7xx series offers ultra-low current consumption with an Iq of only 6 µA (Typ.)

Both families are ideal for applications requiring a direct connection to the battery and low current consumption. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, these ICs also feature over-current 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.

Features and Benefits

  • BD7xx Series: ultra-low quiescent current: 6 µA (Typ.)
  • BD7xx Series: low saturation Pch DMOS 3 to 200 mA; 2 to 500 mA (Typ.)
  • BD4xx Series: low quiescent current: 40 µA (Typ.)
  • BD4xx Series: low saturation Pch DMOS 1.6 to 200 mA; 0.6 to 500 mA (Typ.)
  • VCC maximum voltage: 50 V
  • Output current: 200 mA (maximum) / 500 mA (maximum)
  • Output voltage: 3.3 V ± 2% / 5.0 V ±2%
  • Enables low ESR ceramic capacitors to be used for output phase compensation
  • Integrated output current control circuit protects the IC against damage due to short circuits
  • Built-in thermal shutdown prevents IC overheating due to overload conditions
