The 225 µA quiescent current (325 µA max supply) keeps the idle draw low enough for always-on rails in battery-backed or energy-harvesting designs. ## 60 dB PSRR — what it rejects and where it stops Power-supply rejection is 60 dB at 1 kHz — that attenuates a 100 mV ripple on the input to 100 µV at the output at that frequency. Above the regulator's control-loop bandwidth, PSRR rolls off; a switching converter running at 500 kHz will see much less rejection, so post-filtering or a second-stage LC filter may be needed if the load is noise-sensitive (analog front-end, ADC reference). The 60 dB figure is typical, not guaranteed minimum — derate for temperature and load current per the datasheet curves. ## Protection set — over-current, over-temp, reverse polarity, UVLO The TPS72525KTTRG3 integrates over-current limiting, thermal shutdown, reverse-polarity protection, and under-voltage lockout (UVLO). The UVLO prevents the output from turning on until the input rail is high enough to keep the pass device in regulation — avoids glitched start-up on a slowly rising supply. Reverse-polarity protection clamps the input if the rail is accidentally reversed, which matters in field-service or battery-cable scenarios where the connector is not keyed. ## DDPAK/TO-263-5 — thermal and footprint reality The TO-263-6 (D²Pak, 5 leads plus tab) package is a surface-mount power package with an exposed metal tab on the bottom. The tab is the thermal path — it must be soldered to a copper pad on the PCB, and the pad should connect to a via array or a copper plane to pull heat away. At 1 A with a 0.28 V dropout, the power dissipated is 280 mW; with the tab at 25°C ambient, the junction stays well below 125°C, but in a 85°C enclosure the thermal budget shrinks. The Enable and Reset control pins let the system sequence the 2.5 V rail and hold the downstream load in reset until the output is stable.","metaTitle":"TPS72525KTTRG3 LDO 2.5V 1A, 60dB PSRR, DDPAK-5","metaDescription":"Texas Instruments TPS72525KTTRG3 linear regulator, 2.5V fixed output, 1A, 0.28V dropout at full load, 60dB PSRR at 1kHz, -40°C to 125°C, active production","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"PSRR":"60dB (1kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-263-6, D²Pak (5 Leads + Tab), TO-263BA","lifecycle_stage":"eol_hot","Control Features":"Enable, Reset","Current - Output":"1A","Protection Features":"Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"6V","Voltage Dropout (Max)":"0.28V @ 1A","Current - Supply (Max)":"325 µA","Supplier Device Package":"DDPAK/TO-263-5","Current - Quiescent (Iq)":"225 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.17","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.17000","currency":"USD"},{"qty":10,"price":"$3.74900","currency":"USD"},{"qty":25,"price":"$3.54400","currency":"USD"},{"qty":100,"price":"$3.07160","currency":"USD"},{"qty":250,"price":"$2.91404","currency":"USD"},{"qty":500,"price":"$2.61476","currency":"USD"},{"qty":1000,"price":"$2.22900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/168ba8db77fcdd4a2cd75e8fd0f1bf90.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of TPS72525KTTRG3 at 1 kHz?","answer":"The typical PSRR is 60 dB at 1 kHz.
