LP2951: About Magnetic Field Immune

Part Number: LP2951
Other Parts Discussed in Thread: TLV7011

Hi Ti.

My customer is designing using LP2951(LDO) and TLV7011(OPAMP).

And they using Neodymium Magnet.

My customer want to know Magnetic Field Immune of LP2951(LDO) and TLV7011(OPAMP).

When LP2951(LDO) and TLV7011(OPAMP) are close to Neodymium Magnet for a long time, it's specification is no effect from magnetic filed?

Please let me know.

    Hi SS,

    We did not pursue magnetic field immunity testing on LP2951. This is not a common test for linear regulators. We highly recommend that a prototype be built and sufficient testing be done on the prototype as the strength of the magnetic field will depend on application specific factors such as distance to the magnet and any shielding.

    It is recommended that each E2E thread be restricted to a single TI device for the quickest support. Here is the link for your TLV7011 thread for quicker reference:

    Very Respectfully,
