The 28V maximum input voltage lets it regulate from a 12V or 24V nominal bus — common in automotive and industrial control panels — without a pre-regulator. Maximum dropout is 0.5V at full load, so the input rail needs only 5.5V minimum to maintain regulation; a 12V battery dipped to 6V during cranking still holds the output steady. ## Quiescent current and protection set Quiescent current is 100 µA typical, rising to 10 mA maximum supply current under full load — the low idle draw suits always-on modules in an ECU or sensor node that stay powered during key-off. On-chip protection covers over-current, over-temperature, and short-circuit events; the Enable and Reset control pins allow the system supervisor to sequence the rail and monitor its health.","metaTitle":"MAX5091AATA+T LDO Regulator, 5V Fixed Output, 100mA, 8-TDFN","metaDescription":"Analog Devices MAX5091AATA+T linear regulator, 5V fixed output, 100mA, 28V input max, 0.5V dropout, -40 to +125°C, 8-TDFN.
