It comes in a SOT-23-5 package and is surface-mount only. ## Protection features and temperature range On-chip protection includes over-current, over-temperature, and under-voltage lockout (UVLO). The UVLO keeps the output off until the input voltage rises above the threshold, which prevents the load from seeing a brown-out condition during startup. The operating junction temperature range is -40°C to 125°C, so this part is comfortable in an outdoor telecom enclosure, an engine bay, or a hot industrial cabinet. No derating needed up to the full 200 mA across that range, as long as the PCB copper area can sink the heat. ## Enable pin and control A dedicated Enable pin lets you shut down the regulator to near-zero current draw — the 300 nA quiescent drops to effectively zero when the enable pin is pulled low. ## Sourcing and lifecycle The TPS7A0322PDBVR is listed as Active with ROHS3 compliance. It is available through independent distribution; we source and quote it to order against an RFQ.","metaTitle":"TI TPS7A0322PDBVR LDO Regulator, 2.2V Fixed, 200mA, SOT-23-5","metaDescription":"Texas Instruments TPS7A0322PDBVR is a 2.2V fixed-output LDO rated for 200mA with 300 nA quiescent current, 55dB PSRR at 1kHz, and -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"55dB (1kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"200mA","Protection Features":"Over Current, Over Temperature, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"6V","Voltage Dropout (Max)":"0.45V @ 200mA","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"300 nA","Voltage - Output (Min/Fixed)":"2.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.94000","currency":"USD"},{"qty":10,"price":"$0.83800","currency":"USD"},{"qty":25,"price":"$0.79560","currency":"USD"},{"qty":100,"price":"$0.65340","currency":"USD"},{"qty":250,"price":"$0.61076","currency":"USD"},{"qty":500,"price":"$0.53976","currency":"USD"},{"qty":1000,"price":"$0.42612","currency":"USD"},{"qty":3000,"price":"$0.40200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/619f97c74ffd6e7d6600a49234e51e8d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can TPS7A0322PDBVR be used in battery-powered devices?","answer":"Yes, the 300 nA quiescent current makes it well-suited for battery-powered designs — always-on sensor nodes, wearables, or IoT endpoints where every microamp matters. The 2.2 V output is common for low-power MCUs and RF transceivers. The enable pin lets you shut it down completely when the system sleeps."},{"question":"What is TPS7A0322PDBVR's PSRR at 1 kHz?","answer":"The listed PSRR is 55 dB at 1 kHz. That means ripple on the input is attenuated by a factor of about 560 at that frequency. It is high enough to clean up a switching regulator's output for sensitive analog loads."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS7A0322PDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS7A0322PDBVR when reusing this data.
