LTC1701ES5#TRMPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC1701ES5#TRMPBF is a synchronous buck switching regulator IC manufactured by Analog Devices Inc. It operates at a fixed 1MHz switching frequency and provides a positive adjustable output voltage ranging from 1.25V to the input rail. The device supports up to 500mA of output current and accepts an input voltage range of 3.6V to 40V. Packaged in a compact TSOT-23-5 surface-mount case, it integrates high-side and low-side power switches for efficient DC/DC conversion.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRMPBF confirms the tape-and-reel packaging format and lead-free (PbF) compliance status required for your assembly process. Confirm that the TSOT-23-5 package dimensions match your PCB footprint design. Ensure the operating temperature range meets your environmental specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck solution is needed for inputs up to 40V. The 1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 500mA current rating satisfies the load requirements. Consider thermal performance in the TSOT-23-5 package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC1701 family of synchronous buck regulators. It shares functional similarities with other Analog Devices PMICs but is distinguished by its specific 1MHz frequency and 40V input capability. The ES5 suffix denotes the TSOT-23-5 package variant, differentiating it from larger package options within the same product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitutes include LT1761ES5#TRMPBF and LT1931ES5#TRMPBF. Verify topology compatibility as these may differ in configuration. Check pinout alignment and electrical parameter overlaps before substituting.
