Description

General part information

BD933N5EFJ-C Series

BD933N5EFJ-C is linear regulators using the Nano Cap™ topology designed as low current consumption products for power supplies in various automotive applications requiring a direct connection to the battery. This product is designed for up to 45V as an absolute maximum voltage and to operate until 500mA for theoutput current with low current consumption 25μA (Typ). This can regulate the output with a very high accuracy ±2.0%.What is Nano Cap™?Nano Cap™ is a combination of technologies which allow stable operation even if output capacitance is connected with the range of nF unit.What is QuiCur™?QuiCur™ is a combination of technologies that provides high-speed load response.
