Regulator families boast low quiescent current

-February 06, 2013

Rohm Semiconductors has introduced two series of linear and switching regulators that it says significantly reduce current consumption during standby, making the devices suitable for applications requiring a direct connection to a battery. Both series are qualified to AEC-Q100 automotive requirements.

Housed in HTSOP-J8 packages, the BD7xxLx series of LDO (low-dropout) linear regulators have an absolute maximum voltage rating of 45 V, output voltage accuracy of ±2%, output current of 200 mA or 500 mA, and typical quiescent current consumption of 6.5 µA. Low saturation voltage is achieved by using a PMOS output transistor, and ceramic capacitors can be used for compensation of the output capacitor phase.

Supplied in HTSSOP-B24 packages, the BD9901x series of DC/DC regulators offer a maximum input voltage of 42 V, output current of 2 A, and a typical quiescent current consumption of 22 µA. The devices feature integrated power MOSFETs, and the switching frequency can be scaled from 200 kHz to 500 kHz.

Datasheets for these parts were not available at the time of this announcement.
