ROHM Semiconductor BD9xxN1-C Fixed / Adjustable Output Nano Cap™ LDO Regulators are linear regulators using the Nano CapTM topology. These are designed as low-current consumption products for power supplies in various automotive applications requiring a direct connection to the battery. These products are designed for up to 45V as an absolute maximum voltage and operate until 150mA for the output current. The devices have low current consumption of 28μA (Typ). These can regulate the output with very high accuracy of ±2.0%.
An output capacitor of 100nF (typ.) or more can be used for this product series, and it can realize a brilliant transient characteristic even with small capacitance. The output voltage line-ups are 3.3V, 5.0V, and adjustable type by an external resistive divider. The output voltage can be adjusted between 1.0V and 18V by an external resistive divider connected to the ADJ pin. Enable feature is integrated into the devices. A logical “HIGH” at the EN pin turns on the device, and the ROHM Semiconductor BD9xxN1-C devices are controlled to disable by a logical “LOW” input to the EN pin.
