Quiescent current is 2.6 µA typical, and the maximum supply current is 9 µA — the regulator's own draw is below the self-discharge rate of most coin cells, so it can sit on a sensor node's always-on rail without eating into the battery budget. ## PSRR across the frequency band — what the curve tells you PSRR is specified at 60 dB at 1 kHz, rolling off to 35 dB at 1.5 MHz — the 60 dB figure at audio frequencies means it rejects 100/120 Hz ripple from a mains-derived rectifier well, but above a few hundred kHz the attenuation drops, so if your upstream converter switches at 1 MHz or higher, you will see some of that ripple on the output unless you add a post-filter capacitor with low ESL. ## Package, temperature, and protection — field-fit checklist Operating temperature range is -40 to +125 °C junction, which covers both automotive under-hood and industrial motor-drive environments. Protection features include over-current, over-temperature, and UVLO — the UVLO threshold prevents the output from sourcing current when the input rail is too low to regulate, which avoids brown-out behaviour on the downstream load.","metaTitle":"TI TPS7A1025PDSER LDO, 2.5V Fixed Output, 300mA, 6-WSON","metaDescription":"Texas Instruments TPS7A1025PDSER LDO, fixed 2.5V output, 300mA, ultra-low 2.6 µA Iq, 90mV dropout at full load, PSRR 60dB at 1kHz, -40 to +125°C, 6-WSON.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"PSRR":"60dB ~ 35dB (1kHz ~ 1.5MHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WFDFN","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"300mA","Protection Features":"Over Current, Over Temperature, UVLO","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"3.3V","Voltage Dropout (Max)":"0.09V @ 300mA","Current - Supply (Max)":"9 µA","Supplier Device Package":"6-WSON (1.5x1.5)","Current - Quiescent (Iq)":"2.6 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.01000","currency":"USD"},{"qty":10,"price":"$0.90700","currency":"USD"},{"qty":25,"price":"$0.86080","currency":"USD"},{"qty":100,"price":"$0.70700","currency":"USD"},{"qty":250,"price":"$0.66092","currency":"USD"},{"qty":500,"price":"$0.58406","currency":"USD"},{"qty":1000,"price":"$0.46110","currency":"USD"},{"qty":3000,"price":"$0.43500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/91a2070fe9e5a434d35f71b7edd2c4e3.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS7A1025PDSER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS7A1025PDSER when reusing this data.
