Regulator families boast low quiescent current
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.
