That means you can skip external current-limit resistors and watchdog supervisors for many point-of-load designs. The Enable pin lets you sequence rails, and the Power Good output signals when the output is within regulation — useful for FPGA core sequencing or reset generation. ## Temperature grade and deployment environment Rated for -40°C to 85°C operating ambient, this part suits industrial control cabinets, outdoor telecom enclosures, and automotive cabin electronics. The exposed pad must be soldered to a thermal land on the PCB; without adequate copper area, the junction temperature will limit output current well before the 4A rating. ## Sourcing and lifecycle The part is available through independent distribution channels; pricing and lead time are confirmed at quote time against an RFQ. For dual-sourcing resilience, check pin-compatible siblings in the same family — same footprint, different current grades.","metaTitle":"MAX8556ETE+T LDO Regulator, 4A Adjustable, 16-TQFN","metaDescription":"MAX8556ETE+T adjustable LDO from Analog Devices delivers 4A output with 0.2V dropout max.

No discontinuation notice or last-time-buy schedule is in effect."},{"question":"Does MAX8556ETE+T require a heat sink?","answer":"The 16-WQFN exposed pad package is designed to dissipate heat through the PCB copper plane. Whether an additional heatsink is needed depends on the input-to-output differential, ambient temperature, and PCB layout. At 4A with 0.2V dropout, dissipation is roughly 0.8W; at higher differentials, thermal design becomes critical."},{"question":"Is MAX8556ETE+T pin compatible with MAX8555?","answer":"The MAX8555 and MAX8556 share the same pinout and package (16-TQFN 5x5). The key difference is output current rating — the MAX8555 is a lower-current variant. Check the respective datasheets for exact current limits before substituting."},{"question":"What is the closest pin-compatible alternative to MAX8556ETE+T?","answer":"Within the same family, the MAX8555 is pin-compatible but rated for lower output current. For a direct 4A replacement, stick with the MAX8556. No second-source manufacturer lists a drop-in alternate for this exact part number."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX8556ETET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX8556ETET when reusing this data.
