LMR36500P5RPER

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36500 is a high-efficiency, wide-input voltage synchronous buck converter from Texas Instruments. It integrates a 42V N-channel power switch and operates over an input voltage range of 4.5V to 42V. The device delivers up to 1A output current with adjustable output voltage. It features fixed-frequency operation at 500kHz or 750kHz, selectable via an external resistor. Key protections include overcurrent protection, thermal shutdown, and undervoltage lockout. The controller supports pulse-by-pulse current limiting and ensures stable performance across varying load and line conditions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix P5RPER against the manufacturer's official datasheet to confirm package type (SOT-23-5) and tape-and-reel quantity. Ensure compatibility with your PCB footprint and reflow profile specifications. Cross-reference the date code and lot traceability requirements with your supply chain standards before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for moderate current applications with high input voltages. Consider the fixed switching frequency options to optimize inductor size and EMI filtering. Evaluate thermal performance based on ambient temperature and board copper area, as the SOT-23-5 package has limited heat dissipation capabilities compared to larger packages.
