LT1507CN8#PBF

Overview

The LT1507CN8#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates in a buck topology with an input voltage range of 4 V to 15 V and provides an adjustable output voltage between 2.42 V and 14.88 V. The device supports a maximum output current of 1.5 A and features a fixed switching frequency of 500 kHz. It includes shutdown functionality and draws a typical operating supply current of 3.8 mA. The component is housed in an 8-pin PDIP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

Integrates a complete buck converter circuit including the power switch, control logic, and reference.
Features a fixed 500 kHz switching frequency to minimize external passive component size.
Includes a shutdown pin for low-power standby operation.

Applications

Battery-powered systems requiring efficient step-down conversion
Post-regulation for higher voltage bus rails
General-purpose DC-DC power supplies

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the PDIP-8 through-hole package availability as surface-mount variants exist within the same family. Check manufacturer lifecycle status for long-term supply assurance.

Selection Notes

Select this part for applications requiring a simple, single-output buck solution with through-hole mounting. Ensure the required output current does not exceed 1.5 A and the input voltage remains within the 4 V to 15 V range. Consider thermal management requirements for the PDIP package at full load.

Part Context

This component belongs to the LT1507 series of monolithic step-down switching regulators. It is functionally similar to other parts in the family but distinguished by its PDIP-8 package and industrial temperature rating. Other variants include SOIC packages or different temperature grades.
