PSRR runs 70 dB at 1 kHz down to 40 dB at 10 Hz. That 70 dB at switching frequencies means this LDO knocks down ripple from a downstream buck converter by a factor of about 3000 — useful for feeding a quiet analog rail like an ADC reference or a sensor bias. Quiescent current is 55 µA typical. For a battery-powered device that spends most of its time in a low-power state, that idle draw is low enough to keep the regulator always on without draining the cell overnight. ## Protection set and temp range Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protection. The UVLO prevents the output from sourcing a partially regulated voltage during startup or brownout — the load sees a clean ramp or nothing. That covers industrial enclosures, outdoor telecom cabinets, and under-hood electronics that see moderate heat, but not the 125°C+ of an engine bay or downhole tool. ## 5-DFNB footprint — board-fit note That tiny footprint fits into wearable, IoT, and handheld designs where board real estate is tight. ## Compliance and regulatory acceptance ROHS3 compliant — no restricted substances in the bill of materials, covering EU RoHS directive 2011/65/EU and its amendments. This is the standard environmental compliance for commercial and industrial electronics sold into European markets.","metaTitle":"Toshiba TCR5AM12,LF LDO Regulator, 1.2V 500mA 5DFNB","metaDescription":"Active Toshiba TCR5AM12,LF linear regulator: 1.2V fixed output, 500mA, 70dB PSRR, 55µA Iq, 0.27V dropout max, 5-DFNB package.

That 70 dB at 1 kHz means the LDO attenuates ripple on the input by roughly 3000:1 at that frequency — enough to clean up a noisy 3.3 V rail for a sensitive analog load."},{"question":"What is the closest functional second-source to TCR5AM12,LF?","answer":"The TCR5RG12A,LF is the closest peer — same 500 mA output current, same 1.2 V fixed output, same 5.5 V max input, same 5-DFNB package footprint. The main difference is PSRR: the TCR5RG series offers 100 dB at 1 kHz, which is about 10 dB better than the TCR5AM's 70 dB. For a noise-critical rail that extra rejection may matter; for a general-purpose 1.2 V bus the TCR5AM is sufficient."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TCR5AM12~6LF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TCR5AM12~6LF when reusing this data.
