BD3573YFP-M
500mA 3.3V, Fixed Output, High-Accuracy LDO Regulator for Automotive

BD357xYFP BD357xYHFP Series regulators feature a high withstand voltage (50V) and are suitable to use with onboard vehicle microcontrollers. They offer an output current of 500 mA while limiting the quiescent current to 30µA (Typ). With these devices, a ceramic capacitor may be used at the output for stable operation. The output tolerance is within ±2% over their operating temperature range (-40°C to+125°C). The short circuit protection is folded-type to minimize generation of heat during malfunction. These devices are developed to offer the most robust power supply design under harsh automotive environments. The BD357xYFP BD357xYHFP Series provide an ideal solution to lower current consumption as well as to simplify the use with battery direct-coupled systems.
