LM22676TJE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22676TJE-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator featuring a fixed 5 V output and a maximum 3 A output current. It operates with an input voltage range of 4.5 V to 42 V and utilizes a 500 kHz switching frequency. The device is housed in a TO-263-7 (TO-263) surface-mount package with seven pins. It supports a junction temperature range from -40 °C to +125 °C and incorporates internal compensation for simplified design.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 5 V output option simplifies component selection and layout
• Internal frequency compensation reduces external component count
• Precision enable pin allows for system sequencing and power management

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded processors
• Industrial control system power distribution
• Telecommunications equipment bias supplies
• General-purpose DC-DC conversion modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer specifications. Confirm the 'TJE' designation corresponds to the specific TO-263-7 thin package variant. Ensure ordering documentation matches the fixed 5.0 V output configuration distinct from adjustable versions within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V rail is required with up to 3 A load capability. The wide 42 V input range accommodates standard industrial bus voltages. The TO-263 package offers thermal performance suitable for moderate power densities without requiring extensive heatsinking compared to smaller packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22676 family of SIMPLE SWITCHER regulators, which are designed for ease of use with minimal external components. The family includes variants with different output voltages and packages, such as the SO-PowerPAD-8 and adjustable TO-263 options, all sharing the core buck topology and control architecture.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22676TJ-ADJ/NOPB provides adjustable output in the same TO-263 package. LM22676QMRE-5.0/NOPB offers the same electrical specifications in an 8-SO-PowerPAD package. Cross-reference pinouts and thermal pad connections before substitution.
