Switching regulators tout low stand-by current

Keywords:dark current  linear regulator  switching regulator 

ROHM has developed new compact, high precision, low dark current regulators that utilise a proprietary circuit design to reduce current consumption during stand-by.

The new linear regulators and switching regulators based on innovative low quiescent current technology are available in two different versions.

The BD7xxLx series in a HTSOP-J8 package is a family of low quiescent current linear regulators featuring 45 V absolute maximum voltage, an output voltage accuracy of ±2 per cent, 200mA or 500mA output current and 6.5μA (Typ.) current consumption. Low saturation voltage is achieved by using a PMOS output transistor and ceramic capacitors can be used for compensation of the output capacitor phase.

The BD9901x series in a HTSSOP-B24 package offers low Iq DCDC regulators for a maximum input voltage of 42V, 2A output current and a quiescent current consumption of typ. 22μA. Integrated MOSFETs serve as synchronous rectifier and the switching frequency is scaled from 200kHz to 500kHz. In addition, the line-up features current mode control.

The LDO series is already available in OEM quantities. The Low Iq switching regulators are available in sample quantities. OEM quantities will be available in February 2013.
