Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix requirements, as the SGR117AT may be part of a broader family including variants like SGR117AIG-883B. Confirm radiation hardness levels and packaging details against official Microchip datasheets before ordering. Ensure compatibility with system thermal and electrical constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when radiation tolerance is critical. Compare line regulation and dropout voltage against standard LM317 equivalents if non-radiation environments are considered. Verify that the 1.5 A output current meets load requirements without excessive heat dissipation in the chosen enclosure.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This regulator belongs to Microchip's specialized rad-hard power management portfolio. It serves as a robust alternative to commercial-grade regulators in defense and space sectors where single-event effects and total ionizing dose resistance are mandatory design criteria.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include the SGR117AIG-883B. Standard commercial LM317 devices lack radiation hardness and should not be used in qualifying environments without rigorous testing.
