Product details

Automotive LDO for noise-sensitive supply rails

The TPS7B8601DQDDARQ1 is an adjustable-output low-dropout linear regulator from Texas Instruments, part of the Automotive, AEC-Q100 series. It delivers up to 500 mA from a 40 V maximum input, making it suited for directly regulating battery voltage in automotive body electronics, infotainment, and ADAS sensor modules. With a 70 dB PSRR at 1 kHz, this LDO attenuates ripple from upstream switching converters or alternator noise, keeping the downstream analog or RF supply clean. The 26 µA quiescent current keeps the regulator's own draw low on always-on battery lines.

Wide input range and thermal package

The input voltage range extends to 40 V, covering automotive cold-crank dips and load-dump transients without an external clamp. The adjustable output is set between 1.2 V and 18 V via an external resistor divider. The 8-PowerSOIC package with an exposed PowerPad (8-SO PowerPad) pulls heat into the PCB copper plane. The 0.570 V maximum dropout at 500 mA means the input-to-output headroom must stay above that threshold to maintain regulation at full load. Operating temperature spans -40°C to 125°C ambient, matching the AEC-Q100 Grade 1 automotive qualification. Protection features include overcurrent, overtemperature, and undervoltage lockout (UVLO).

Active lifecycle and sourcing posture

Texas Instruments lists the TPS7B8601DQDDARQ1 as Active, with ROHS3 compliance.

Frequently asked questions

What is the PSRR of TPS7B8601DQDDARQ1?

The PSRR is 70 dB at 1 kHz, which means it attenuates ripple at that frequency by a factor of about 3160, keeping the output clean for noise-sensitive analog or RF loads.

Can TPS7B8601DQDDARQ1 replace TPS70612DBVT?

No, the TPS70612DBVT is a fixed 1.2 V output LDO with a 150 mA rating and 6.5 V maximum input. The TPS7B8601DQDDARQ1 is adjustable, handles 500 mA, and accepts up to 40 V input, so the two are not pin-compatible or drop-in replacements. A board-level redesign would be needed.
