It is designed for space-constrained, noise-sensitive applications such as RF transceivers, sensor front-ends, and MCU core supplies where a clean, regulated rail is required. ## Protection features and operating range Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protection cover the common fault conditions. UVLO prevents the output from turning on until the input voltage is high enough to regulate, avoiding brown-out operation. The -40°C to 125°C junction temperature range covers automotive under-hood and industrial enclosure environments without derating at the low end.","metaTitle":"TI TLV755185PDQNR LDO Regulator, 1.85V Fixed, 500mA, 4-X2SON","metaDescription":"Texas Instruments TLV755185PDQNR LDO: fixed 1.85V output, 500mA, 0.4V dropout at full load, PSRR 52dB (1kHz-1MHz), -40°C to 125°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"52dB (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":"500mA","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)":"0.4V @ 500mA","Supplier Device Package":"4-X2SON (1x1)","Current - Quiescent (Iq)":"40 µA","Voltage - Output (Min/Fixed)":"1.85V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.39400","currency":"USD"},{"qty":25,"price":"$0.36720","currency":"USD"},{"qty":100,"price":"$0.29380","currency":"USD"},{"qty":250,"price":"$0.27284","currency":"USD"},{"qty":500,"price":"$0.23086","currency":"USD"},{"qty":1000,"price":"$0.17840","currency":"USD"},{"qty":3000,"price":"$0.16266","currency":"USD"},{"qty":6000,"price":"$0.15216","currency":"USD"},{"qty":15000,"price":"$0.14850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bf418b76719212d179fb828e8ede085b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TLV755185PDQNR compatible with 3.3V input?","answer":"Yes.
