1A Fixed Output LDO Regulators - BD30IC0WEFJ

BDxxIC0W series are a LDO regulator with output current 1.0A. The output accuracy is ±1% of output voltage. Withexternal resistance, it is available to set the output voltage at random (from 0.8V to 4.5V) and also provides output voltagefixed type without external resistance. It is used for the wide applications of digital appliances. It has package type:HTSOP-J8 and HVSOF6. Over current protection (for protecting the IC destruction by output short circuit), circuit currentON/OFF switch (for setting the circuit 0µA at shutdown mode), and thermal shutdown circuit (for protecting IC from heatdestruction by over load condition) are all built in. It is usable for ceramic capacitor and enables to improve smaller set andlong-life.

* This is STANDARD grade product. For on-vehicle usage, please contact Sales.
