The SPX1587 is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost effective, small footprint solution.
This device is an excellent choice for use in battery powered applications and portable computers. The SPX1587 features very low quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases, quiescent current flows into the load, increasing efficiency. The SPX1587 is available in adjustable or fixed 1.5V, 2.5V, 3.3V and 5.0V output voltages.
The SPX1587 is offered in several 3-pin surface mount packages: TO-252, TO-220 and TO-263. A 10μF ceramic or tantalum output capacitor provides unconditional stability.
- Guaranteed 3A output current
- Three terminal adjustable or fixed
- 1.5V, 2.5V, 3.3V and 5.0V
- Low quiescent current
- Low dropout voltage: 1.1V at 3A
- Line regulation: 0.1%
- Load regulation: 0.1%
- Stable with 10uF ceramic capacitor
- Overcurrent and thermal protection
- Available packages: TO252, TO220 and 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 |
