QuiCur™ Automotive 500mA Buck LDO Regulators

ROHM Semiconductor QuiCur™ Automotive 500mA Buck LDO Regulators are ideal for automotive applications directly connected to the battery. The ROHM Semiconductor QuiCur regulators support up to 45V maximum voltage, operate up to 500mA output current, and feature low current consumption at 9.5μA (typical). Achieving a high accuracy of ±2.0%, the output voltage options include 3.3V, 5.0V, and adjustable types ranging from 1.0V to 16V via an external resistive divider connected to the ADJ pin.
