BD433M5FP-C
500mA 3.3V, Fixed Output, Low Iq, High-Accuracy LDO Regulator for Automotive

The BD433M5FP-C is low quiescent regulator. This regulator is therefore ideal for applications requiring a direct connection to the battery and a low current consumption. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, this IC also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.
