It ships with a fixed 3.3 V output but can be configured as adjustable down to 1.25 V via external resistors — one device covers both a dedicated 3.3 V rail and a generic low-voltage supply on the same BOM line. ## Dropout and quiescent budget Maximum dropout is 155 mV at the full 300 mA load (typical), which means the input rail needs only 3.455 V to maintain regulation on the 3.3 V output — a 5 V rail with a Schottky diode drop still has margin. The 270 µA quiescent current (Iq) sets the standing power draw; in a battery-powered sensor waking once per second, the regulator's own consumption dominates the sleep budget more than the load. Input voltage range extends to 6.5 V max, so the part runs comfortably from a 5 V ±10 % supply or a single Li-ion cell. The 6.5 V output maximum (adjustable mode) mirrors the input ceiling — the pass FET saturates before the output can exceed the input. ## Protection and control interface On-chip protection covers over-temperature, reverse polarity, and short-circuit events — the regulator shuts down before the junction exceeds the die rating, and the reverse-polarity clamp prevents damage if the input is accidentally reversed. The enable pin allows the regulator to be gated by a GPIO or a power-good signal from an upstream converter; the fault output (active-low open-drain) asserts when the output drops out of regulation, which can drive a reset line or a status LED. Housed in the 8-uMAX/uSOP package (3.00 mm width, 0.118\" pitch), the part is a surface-mount fit for compact PCBs.","metaTitle":"MAX8860EUA33+ LDO Regulator, 300 mA, 3.3 V Fixed, 8-uMAX","metaDescription":"MAX8860EUA33+ LDO from Analog Devices: 300 mA output, 3.3 V fixed or adjustable, 155 mV dropout, 270 µA Iq, industrial temp.

The MAX8860EUA30 is the 3.0 V fixed version. Both share the same pinout, package, and 300 mA rating — the only difference is the factory-trimmed output voltage. If your circuit expects 3.0 V, the 3.3 V output will overdrive the load by 10 %; check the downstream tolerance before substituting."},{"question":"Does MAX8860EUA33+ require external capacitors?","answer":"Yes, like most LDOs it needs input and output capacitors for stability. The datasheet recommends a 1 µF ceramic on the input and a 1 µF to 10 µF ceramic on the output, placed close to the pins. The output capacitor ESR range is specified to keep the control loop stable across load and temperature."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX8860EUA33","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX8860EUA33 when reusing this data.
