Features |
The SPX1585 is a low power 5A, adjustable and fixed voltage regulator that is very easy to use. It requires only two external resistors to set the output voltage for the adjustable version. The SPX1585 devices are designed for low voltage applications that offer lower dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocessors that require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications. The SPX1585 features low dropout of a maximum 1.2 volts.
The SPX1585 offers full protection against overcurrent faults, reversed input polarity, reversed load insertion and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The IQ of this device flows into the load, which increases efficiency. The SPX1585 devices are offered in a 3-pin TO-220 and TO-263 package compatible with other 3-terminal regulators. For an 8A low dropout regulator, refer to the SPX1584 datasheet.
- Adjustable output down To 1.2,or fixed 3.3V versions
- Output current of 5A
- Low dropout voltage 1.1V typical @ 5A
- Extremely tight load and line regulation
- Current and thermal limiting
- Standard 3-terminal low cost TO263
- Similar to industry standard LT1085/LT1585

07/17/2023 | In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023. | PCN & PDN Download |
