Extended Temperature (H & MP) Switching Regulators
Linear Technology offers several options for applications requiring extended temperature operation.
H-grade products offer 100% testing at hot, typically 125ºC or 150ºC as defined in the datasheet. H-grade products are sample tested at cold (-40ºC) with an expanded sample size and zero allowed failures.
Military plastic (MP) grade products provide a COTS (commercial off the shelf) solution with guaranteed performance over extended operating temperatures for use in applications subject to very harsh environmental conditions. MP grade products are 100% tested at hot (125ºC or 150ºC as specified in the datasheet) AND 100% tested at cold (-55ºC). MP products also offer additional inspection, tighter in-process controls, temperature cycling, enhanced reliability monitoring and are fully characterized over the military temperature range.
