LT1076CT-5#PBF

DC DC Voltage Regulators Overview

The LT1076CT-5#PBF is a monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates in a buck topology with a fixed 5 V output and supports up to 1.6 A output current. The device accepts an input voltage range of 8 V to 45 V, with a minimum operating voltage of 7.3 V. It features a 100 kHz switching frequency and draws 8.5 mA of static current. Housed in a TO-220-5 through-hole package, it functions within a temperature range of 0°C to +70°C.

DC DC Voltage Regulators Feature Summary

• Integrates power switch, oscillator, control circuitry, and current limit components on a single chip
• Supports multiple converter topologies including positive-to-negative, negative boost, and flyback configurations
• Switch output specified to swing 40V below ground for tapped-inductor applications

DC DC Voltage Regulators Applications

• Tapped-inductor buck converters
• Positive-to-negative voltage conversion
• Negative boost converter circuits
• Flyback converter designs

DC DC Voltage Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the TO-220-5 package type matches your PCB footprint requirements. Ensure the 1.6 A output current rating meets your load demands. Check the 0°C to +70°C operating temperature range against your environmental conditions. Validate that the 8 V to 45 V input voltage range aligns with your system supply.

DC DC Voltage Regulators Selection Notes

Select this component when a robust bipolar switching regulator is required for high-current buck applications. The integrated design minimizes external component count compared to discrete solutions. Consider the TO-220-5 package for through-hole mounting needs. Evaluate the 100 kHz switching frequency for EMI constraints. Verify compatibility with tapped-inductor topologies if utilizing the low-side switching capability.

DC DC Voltage Regulators Part Context
