The BD3941FP-E2 from ROHM Semiconductor is a high-precision, low-saturation linear voltage regulator designed for automotive body control systems. It features a fixed 5V output voltage and can deliver up to 500mA of current. The regulator boasts a super-low dark current of 30 µA (typical) and supports the use of low-ESR ceramic capacitors for output phase compensation.
With a high breakdown voltage of 36V, this LDO regulator is compatible with onboard vehicle microcontrollers. It incorporates built-in over-current protection and thermal shutdown circuits for enhanced reliability. The P-channel DMOS output transistors ensure that increased loads do not significantly increase total supply current, making it ideal for lowering current consumption and costs in battery direct-coupled systems.
The BD3941FP-E2 is housed in a TO-252-3, DPAK (2 Leads + Tab), SC-63 surface-mount package, suitable for various automotive equipment, car stereos, and satellite navigation systems. Its operating temperature range is -40°C to +125°C, and it offers a voltage dropout of 0.9V at 200mA.
