Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP2357DT-LF-Z

The MP2357DT-LF-Z is a monolithic step-down switching regulator capable of delivering a peak output current of 0.5A. It operates over a wide input voltage range of 4.5V to 24V and provides an adjustable output voltage from 0.81V to 15V. The device features a fixed switching frequency of 1.4MHz and includes an internal power MOSFET with a low on-resistance of 0.35Oc, contributing to an efficiency of up to 92%. Protection features include thermal shutdown and cycle-by-cycle overcurrent protection, ensuring reliable operation under fault conditions. The regulator is designed to work with low ESR output ceramic capacitors, simplifying the external component requirements. It is available in both TSOT23-6 and SOT23-6 packages and operates within a temperature range of -40¬8C to +85¬8C. This product is suitable for applications such as distributed power systems, battery chargers, and as a pre-regulator for linear regulators.
