It pulls just 3 µA quiescent current, making it a candidate for battery-powered or always-on rails where every microamp counts. The 40 dB PSRR holds flat from 1 kHz to 1 MHz, so it cleans up switching-regulator ripple across a wide band — useful for analog or RF front-end supplies that can't tolerate noise. ## Protection and control Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protect the load and the regulator itself. The Enable pin lets a microcontroller or power sequencer gate the output — no external load-switch needed for a 200 mA rail. ## Temperature range and environment Rated for junction temperature from -40°C to 125°C. That covers automotive under-hood, outdoor telecom cabinets, and industrial enclosures where the board sees thermal cycling. The 4-X2SON with exposed pad helps pull heat into the PCB copper — no heatsink, but the board layout needs a thermal via under the pad.","metaTitle":"TPS7A0528PDQNT LDO Regulator, 2.8V Fixed, 200mA, 40dB PSRR","metaDescription":"TI TPS7A0528PDQNT LDO: 2.8V fixed output, 200mA, 40dB PSRR (1kHz-1MHz), 3µA Iq, -40°C to 125°C, 4-X2SON.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"40dB (1kHz ~ 1MHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"4-XDFN Exposed Pad","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)":"5.5V","Voltage Dropout (Max)":"0.308V @ 200mA","Supplier Device Package":"4-X2SON (1x1)","Current - Quiescent (Iq)":"3 µA","Voltage - Output (Min/Fixed)":"2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.37000","currency":"USD"},{"qty":10,"price":"$1.22300","currency":"USD"},{"qty":25,"price":"$1.16040","currency":"USD"},{"qty":100,"price":"$0.95330","currency":"USD"},{"qty":250,"price":"$0.89108","currency":"USD"},{"qty":500,"price":"$0.78748","currency":"USD"},{"qty":1250,"price":"$0.62169","currency":"USD"},{"qty":2500,"price":"$0.58650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61fd9c96a864f4de9f6a1ff807cd90f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TPS7A0528PDQNT a replacement for TPS7A0528PDRVR?","answer":"The TPS7A0528PDRVR is the same regulator in a 4-X2SON package with the same 1x1 mm footprint and identical electrical specs.
