Its 15 µA quiescent current makes it a fit for always-on rails in battery-powered or energy-conscious designs — the regulator's own draw stays below 20 µA even at light load, preserving standby budget. ## PSRR profile and noise rejection PSRR is specified at 65 dB at 100 Hz, rolling off to 40 dB at 1 MHz. This means the LDO attenuates low-frequency ripple from a switching pre-regulator by a factor of ~1800 at 100 Hz, but above 100 kHz the rejection drops to about 100× — upstream noise above that corner passes through unless filtered ahead of the LDO input. ## Dropout and headroom Maximum dropout voltage is 0.69 V at 300 mA load. The input rail must stay at least 0.69 V above the 0.9 V output across the full load range — a 1.8 V supply provides 0.9 V headroom, well within the 6 V maximum input rating. Below the dropout threshold the output falls out of regulation. ## Temperature range and protection Rated for -40°C to 125°C junction temperature, covering industrial and automotive ambient conditions. On-chip protection includes over-current, over-temperature, and under-voltage lockout (UVLO). The enable pin allows external sequencing; the soft-start feature limits inrush current during power-up.","metaTitle":"TI TPS7A2009PDBVR LDO, 300 mA, 0.9 V Fixed, SOT-23-5","metaDescription":"Texas Instruments TPS7A2009PDBVR LDO, 300 mA output, fixed 0.9 V, 15 µA quiescent current, PSRR 65dB~40dB (100Hz~1MHz), SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"65dB ~ 40dB (100Hz ~ 1MHz)","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, Soft Start","Current - Output":"300mA","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)":"0.69V @ 300mA","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"15 µA","Voltage - Output (Min/Fixed)":"0.9V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.39800","currency":"USD"},{"qty":25,"price":"$0.37120","currency":"USD"},{"qty":100,"price":"$0.29690","currency":"USD"},{"qty":250,"price":"$0.27572","currency":"USD"},{"qty":500,"price":"$0.23332","currency":"USD"},{"qty":1000,"price":"$0.18028","currency":"USD"},{"qty":3000,"price":"$0.16438","currency":"USD"},{"qty":6000,"price":"$0.15377","currency":"USD"},{"qty":15000,"price":"$0.14317","currency":"USD"},{"qty":30000,"price":"$0.13574","currency":"USD"},{"qty":75000,"price":"$0.13256","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7af9499db957bf46087c76a8597de07b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of TPS7A2009PDBVR?","answer":"PSRR is 65 dB at 100 Hz, decreasing to 40 dB at 1 MHz.
