Product details

Temperature range and deployment environment

Rated for -40°C to 125°C operating junction temperature, which covers under-hood, engine bay, and cabin automotive environments. The SOT-23-5 package is a standard surface-mount footprint with good thermal dissipation for 100mA.

Lifecycle and sourcing posture

The TPS76928QDBVRG4Q1 carries an Active product status per the manufacturer — no last-time-buy or end-of-life notice is in effect. It is ROHS3 compliant. A formal quote will confirm lead time and quantity breaks at the time of request.

Frequently asked questions

Does TPS76928QDBVRG4Q1 meet AEC-Q100 automotive qualification?

Yes, the TPS76928QDBVRG4Q1 is part of the Automotive, AEC-Q100 series and is qualified for automotive applications.

What is the closest functional alternative to TPS76928QDBVRG4Q1?

A peer in the same current class is the TPS70612DBVT (150mA, 1.2V fixed output, 80dB to 52dB PSRR over 10 Hz to 1 kHz). The key difference is output voltage and PSRR profile — the TPS76928 delivers 2.8V fixed with 60dB at 1kHz, while the TPS70612 provides a lower 1.2V rail with higher low-frequency PSRR. They are not pin-compatible substitutes; select based on required output voltage and noise rejection at the target frequency.

What is the PSRR of TPS76928QDBVRG4Q1?

The listed PSRR is 60dB at 1kHz, which is adequate for filtering switching-regulator ripple on automotive sensor and transceiver supplies.
