LT1076CR-5#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1076CR-5#PBF is a monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates in a buck topology with a fixed 5V output and supports up to 1.6A continuous output current. The device accepts an input voltage range of 8V to 60V, with a minimum operating voltage of 7.3V. It features a 100kHz switching frequency and includes integrated power switches, oscillator, control circuitry, and current limit components. The unit is housed in a DDPAK-7 surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the DDPAK-7 package variant matches the target PCB footprint. Ensure the supplier provides valid traceability documentation for this Analog Devices component. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit units.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a higher input voltage rail. The 1.6A current rating suits moderate load applications. Consider the thermal performance of the DDPAK-7 package for heat dissipation requirements. Verify that the 100kHz switching frequency aligns with electromagnetic interference constraints in the design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1076 series of high-performance switching regulators. The CR suffix denotes the surface-mount DDPAK-7 package variant. The -5 designation specifies the fixed 5V output version. This series is designed for efficient DC-DC conversion with minimal external component count.
