MP2357DJ-LF-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP2357DJ-LF-P is a non-synchronous step-down switching regulator from Monolithic Power Systems, housed in a TSOT-23-6 package. It accepts an input voltage range of 4.5 V to 24 V and provides an adjustable output voltage between 0.81 V and 15 V with a maximum continuous output current of 500 mA. The device operates at a fixed switching frequency of 1.4 MHz and includes integrated shutdown functionality. It is rated for operation within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-side N-channel MOSFET switch for efficient power conversion.
• Features a fixed 1.4 MHz switching frequency to minimize external component size.
• Includes internal soft-start circuitry to limit inrush current during startup.
• Provides comprehensive protection against over-current, thermal overload, and under-voltage lockout.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring compact power solutions
• Embedded systems with single-supply architectures
• Battery-powered devices needing efficient voltage regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as this component may be subject to lifecycle changes. Ensure the supplier provides valid traceability data for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a small footprint and moderate output current up to 500 mA. Compare against the MP2359 series if higher current capacity is needed. Verify that the 1.4 MHz frequency aligns with electromagnetic interference requirements. Ensure the input voltage range covers the system's operational extremes.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP235x family of synchronous buck converters, though this specific variant is non-synchronous. It shares the TSOT-23-6 form factor with other members like the MP2358 and MP2359. The family targets space-constrained designs requiring reliable DC-DC conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

MP2357DJ-LF-Z is a parameter-equivalent alternative available in tube packaging. Verify pin compatibility and electrical specifications before substitution. Consult the manufacturer for any newer generations replacing this legacy part number.
