Automotive 300mA Fixed Output LDO Regulators - BD3650FP-M

BD3650FP regulators feature a high 36V breakdown voltage and are suitable for use with onboard vehicle microcontrollers. With these devices, a ceramic capacitor can be selected at the output for stable operation, the output tolerance is within ±2% over the wide ambient temperature range (-40 to 125℃), and the short circuit protection is folded-type to minimize generation of heat during malfunction. These devices are developed to offer most robust power-supply design under the harsh automotive environment. The BD3650FP provide ideal solutions to lower the current consumption as well as to simplify the use with battery direct-coupled systems.
