LT1176CN8-5#PBF

Overview

The LT1176CN8-5#PBF is a fixed-output switching regulator IC manufactured by Analog Devices Inc. It operates in buck topology with a fixed 5V output voltage and supports up to 1.2A switch current. The device accepts an input voltage range from 8V to 35V and functions at a switching frequency of 100kHz. It is housed in an 8-PDIP package suitable for through-hole mounting and complies with RoHS3 standards.

Feature Summary

• Provides a fixed 5V regulated output without external adjustment components
• Integrates a high-current internal switch capable of delivering 1.2A
• Operates at a standard 100kHz switching frequency for efficient power conversion

Applications

• General-purpose DC-DC step-down power supply circuits
• Embedded systems requiring stable 5V logic rails
• Industrial control modules with wide input voltage ranges

Procurement Notes

Verify the specific suffix -5#PBF confirms the fixed 5V output variant, distinct from adjustable versions. Confirm the 8-PDIP package matches your PCB footprint requirements. Ensure compliance with RoHS3 directives is required for your assembly process. Check manufacturer documentation for any recent PCN updates regarding packaging or material changes.

Selection Notes

Select this component when a fixed 5V output is required rather than an adjustable one. The 1.2A current rating suits moderate load applications. The through-hole PDIP package is appropriate for prototyping or high-reliability manual assembly. Consider thermal management if operating near maximum current limits.

Part Context

This part belongs to the LT1176 family of switching regulators. It shares the core architecture with adjustable variants but features internal feedback network programming for a fixed 5V output. The CN8 designation indicates the commercial temperature range and PDIP package style.

Replacement Considerations

LT1176CN8#PBF (Adjustable version requires external resistor divider for 5V). LT1176MPS8-5#PBF (SOIC package alternative).
