The 20 µA quiescent current keeps the always-on supply draw low in ECU modules, and the adjustable output from 1.5 V to 5 V covers the common core and I/O voltages for microcontrollers, CAN transceivers, and sensor bias. ## PSRR across frequency — what 60 dB to 40 dB means for a clean rail The PSRR is specified at 60 dB at 100 Hz, dropping to 40 dB at 100 kHz. This profile is typical for an LDO with moderate loop gain; the 60 dB at low frequencies handles 100 Hz / 120 Hz ripple from a rectified input or a switching pre-regulator's fundamental, while the 40 dB at 100 kHz still provides meaningful attenuation of the first few harmonics of a 400 kHz to 2 MHz buck converter. For a 3.3 V analog supply rail fed from a 5 V switching regulator, this PSRR range is sufficient to keep ripple below 1 mVpp if the input ripple is under 100 mVpp. The dropout voltage is 0.45 V maximum at 150 mA, so a 5 V input holds a 3.3 V output with margin even through cold-crank dips to 4.5 V. ## Protection suite and control features The TPS7A6601QDGNRQ1 integrates over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) protection, plus a watchdog monitor on the enable pin. The Power Good output provides a sequenced-rail flag for an MCU or FPGA power-on reset. The Enable pin allows the rail to be gated by a system supervisor. For a safety-critical ECU rail, this protection set reduces external supervisory IC count. ## Package, thermal, and mounting The 8-HVSSOP package (3.00 mm × 3.00 mm body) with an exposed thermal pad is the key to keeping junction temperature under the 150°C limit at full load in a 105°C ambient. The part is surface-mount only, and the tape-and-reel or cut-tape options suit both prototyping and production reels. ## Lifecycle and compliance No NRND or last-time-buy notice is on the public record for this part. The AEC-Q100 qualification is documented; the part is listed under the automotive-grade category.","metaTitle":"TI TPS7A6601QDGNRQ1 LDO Regulator, 150mA, AEC-Q100","metaDescription":"Texas Instruments TPS7A6601QDGNRQ1 adjustable LDO, 150mA output, 40V input, 20µA Iq, PSRR 60dB~40dB (100Hz~100kHz), AEC-Q100, -40°C to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"PSRR":"60dB ~ 40dB (100Hz ~ 100kHz)","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good","Current - Output":"150mA","Protection Features":"Over Current, Over Temperature, Short Circuit, Under Voltage Lockout (UVLO), Watchdog","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 150°C (TJ)","Voltage - Input (Max)":"40V","Voltage Dropout (Max)":"0.45V @ 150mA","Voltage - Output (Max)":"5V","Supplier Device Package":"8-HVSSOP","Current - Quiescent (Iq)":"20 µA","Voltage - Output (Min/Fixed)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.74000","currency":"USD"},{"qty":10,"price":"$1.56300","currency":"USD"},{"qty":25,"price":"$1.47440","currency":"USD"},{"qty":100,"price":"$1.25640","currency":"USD"},{"qty":250,"price":"$1.17968","currency":"USD"},{"qty":500,"price":"$1.03222","currency":"USD"},{"qty":1000,"price":"$0.85527","currency":"USD"},{"qty":2500,"price":"$0.79628","currency":"USD"},{"qty":5000,"price":"$0.76679","currency":"USD"},{"qty":12500,"price":"$0.73730","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ea0c2060e6baa5711f2aef9fd27e2629.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will TPS7A6601QDGNRQ1 drop into a panel specified around TPS7A0313PDBVR without rewiring?","answer":"No, the TPS7A0313PDBVR is a fixed-output 1.3 V LDO with a 6.0 V maximum input and a different pinout and package (SOT-23-5).
