The 73 dB PSRR at 1 kHz means that ripple on the input rail up to 5.5 V is attenuated by a factor of roughly 4500 at that frequency — useful for powering analog front-ends or sensor bias where the upstream supply carries switching noise. ## Dropout and quiescent — the real-world headroom and standby drain Maximum dropout is 0.7 V at 300 mA load — the input rail must stay at least 0.7 V above 1.7 V to maintain regulation at that current. At 200 mA typical load the dropout is lower, but the worst-case figure governs the design margin. Quiescent current is 60 µA typical — the regulator's own draw is low enough for battery-powered equipment that spends most of its time in sleep, though not at the sub-µA level of dedicated ultra-low-Iq parts. The enable pin lets the system shut down the output for power sequencing or standby — when pulled low the output goes high-impedance and the quiescent current drops further. ## Industrial temperature range and protection — where it fits Built-in over-current protection limits the output during a fault — the regulator folds back rather than latching off, so it self-recovers when the overload clears. The SOT-553 footprint is 1.6 mm × 1.6 mm — the smallest package in the TCR2EE family. ## Active lifecycle — no obsolescence risk on this order code RoHS non-compliant — the part contains lead (Pb) above the 0.1% threshold. This is typical for legacy or high-reliability lots that use tin-lead plating. If your BOM requires RoHS compliance, the TCR2EE17,LM(CT does not meet it; a Pb-free variant would carry a different suffix. Sourced through independent distribution channels.","metaTitle":"Toshiba TCR2EE17,LM(CT LDO, 1.7V fixed, 200mA, SOT-553","metaDescription":"Toshiba TCR2EE17,LM(CT linear regulator: 1.7V fixed output, 200mA, 73dB PSRR at 1kHz, SOT-553.

The only difference is the fixed output voltage: TCR2EE17,LM(CT regulates to 1.7 V, while TCR2EE185,LM(CT regulates to 1.85 V. If the downstream load requires exactly 1.85 V, the 1.7 V part will not substitute without a board-level change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TCR2EE17LMCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TCR2EE17LMCT when reusing this data.
