The MT3540-F25 from XIAN Aerosemi Tech is a SOT-23-5 DC-DC converter. It is a low-voltage, cost-effective, high-performance, non-isolated step-down DC-DC solution. It is designed to deliver up to 500 mA of current from a 3.5 V to 25 V input range with ultra-low quiescent current, high efficiency, and low voltage ripple. The device is inherently protected with a soft-start feature, over-current protection, and thermal shut-down. It is ROHS-compliant and is approved for industrial applications.
