Output voltage is adjustable from a 0.8 V reference up to 3.6 V, making it suitable for powering low-voltage core rails in FPGAs, ASICs, and mixed-signal processors. ## Dropout and PSRR — what they mean for the rail Power-supply rejection ratio is specified at 60 dB at 1 kHz, rolling off to 30 dB at 300 kHz — upstream switching noise above the crossover frequency will couple through unless the LDO input is pre-filtered with a low-ESR ceramic cap. ## Protection and control features Integrated protection includes over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) — the regulator enters a safe state without external supervisory components. Control features — Enable, Power Good, and Soft Start — allow sequenced power-up and fault reporting to a system controller or FPGA.","metaTitle":"TPS74901RGWR LDO Regulator, 3A, Adjustable, 20-VQFN","metaDescription":"Texas Instruments TPS74901RGWR adjustable LDO, 3A output, 0.28V dropout at 3A, PSRR 60dB-30dB (1kHz-300kHz), -40°C to 125°C, 20-VQFN Exposed Pad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"PSRR":"60dB ~ 30dB (1kHz ~ 300kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"20-VQFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good, Soft Start","Current - Output":"3A","Protection Features":"Over Current, Over Temperature, Short Circuit, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.28V @ 3A","Voltage - Output (Max)":"3.6V","Supplier Device Package":"20-VQFN (5x5)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$4.02900","currency":"USD"},{"qty":25,"price":"$3.80880","currency":"USD"},{"qty":100,"price":"$3.30100","currency":"USD"},{"qty":250,"price":"$3.13172","currency":"USD"},{"qty":500,"price":"$2.81008","currency":"USD"},{"qty":1000,"price":"$2.39550","currency":"USD"},{"qty":3000,"price":"$1.87500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/242c47a02d2f57c8a7e3446dd264ee9d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of TPS74901RGWR and why does it matter?","answer":"PSRR is 60 dB at 1 kHz, decreasing to 30 dB at 300 kHz. This means the regulator rejects low-frequency ripple well but passes higher-frequency switching noise — a low-ESR input capacitor is needed to maintain clean output on noise-sensitive analog rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS74901RGWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS74901RGWR when reusing this data.
