Product details

Protection and shutdown for low-power designs

Built-in over-current and over-temperature protection cover the usual fault cases — a shorted load or a stalled fan won't smoke the part. The shutdown control pin lets you drop the quiescent current from 90µA to near zero when the rail is not needed, which is handy for battery-powered gear that sleeps between readings. Operating temperature spans -40°C to 85°C, so it handles outdoor telecom cabinets, factory-floor sensors, and unheated enclosures without issue.

Sourcing and lifecycle — active, no LTB worry

The MAX8511EXK31+T carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

What is the current rating of MAX8511EXK31+T?

The maximum output current is 120mA. It is a low-current LDO sized for sensor bias, small MCU rails, or reference supplies — not for powering a motor or a radio transmitter.

What package is MAX8511EXK31+T in?

It comes in a SC-70-5 package (also known as 5-TSSOP or SOT-353). That is a 5-lead surface-mount package about 2mm x 2.1mm — hand-solderable with a fine iron tip and some flux.

Is there a pin-compatible replacement for MAX8511EXK31+T?

Within the MAX8511 family, other fixed-voltage variants (e.g. 1.8V, 2.5V, 3.3V) share the same SC-70-5 pinout and 120mA rating. For a direct 3.1V replacement, the same order code is the intended part; no second-source alternate is listed in the available records.
