Texas Instruments TPS7B7702QPWPRQ1 – Dual 300‑mA Automotive LDO Regulator, Adjustable 1.5–20 V (HTSSOP‑16, PowerPAD)
The Texas Instruments TPS7B7702QPWPRQ1 is a dual‑channel, automotive‑qualified low‑dropout (LDO) linear regulator designed to simplify multi‑rail post‑regulation in vehicles. Each channel supplies up to 300 mA with an adjustable output from 1.5 V to 20 V, enabling one device to support diverse loads such as body control modules, infotainment subsystems, and instrument clusters. Housed in a compact HTSSOP‑16 (PWP) package with an exposed thermal pad (PowerPAD), this member of the TPS7B770x‑Q1 family prioritizes thermal performance and reliability in harsh automotive environments.
Engineers will appreciate the straightforward integration and BOM consolidation that a dual‑channel LDO like the TPS7B7702QPWPRQ1 offers, while sourcing managers gain assurance from its AEC‑Q100 qualification and RoHS compliance. The tape‑and‑reel option (ordering code suffix R) streamlines automated assembly for high‑volume production.

Typical applications
The TPS7B7702QPWPRQ1 targets multi‑rail automotive post‑regulation where compact size and reliability matter:
- Automotive power rails (post‑regulation from a pre‑regulator or battery)
- Body Control Modules (BCM)
- Infotainment head units and amplifiers
- Digital instrument clusters and driver information systems
- General‑purpose automotive post‑regulation
Each adjustable channel can be configured to support logic rails, sensors, or analog subsystems, enabling creative power partitioning and noise isolation across a vehicle’s electronic architecture.
Design‑in considerations
While detailed electrical characteristics must come from the datasheet, the following general guidelines can streamline the power‑tree design phase:
- Output voltage setting: Use appropriately rated feedback divider components to set each channel within the device’s 1.5–20 V adjustable range.
- Headroom: Ensure the input supply maintains adequate headroom above the programmed VOUT, considering dropout at your expected load and temperature. Dropout voltage is not specified here—refer to the datasheet curves and limits.
- Thermal performance: Fully solder the PowerPAD (exposed thermal pad) to a solid copper area with thermal vias to ground to minimize junction temperature rise. Consider spreading copper under heat‑dissipating components nearby.
- Load distribution: Leverage the two 300‑mA channels to separate noisy digital loads from sensitive analog rails. Place bypass capacitors close to each output pin.
- Transient response: Size output and input capacitors per datasheet guidance to manage load steps and cold‑crank scenarios. Capacitor type, value, and ESR stability guidance are not specified here—use the datasheet recommendations.
- System protection: Current limit, thermal shutdown, and fault reporting (if available) are not specified here; review the datasheet to coordinate with upstream protection and diagnostics.

Sourcing tips for the Texas Instruments TPS7B7702QPWPRQ1:
- For up‑to‑date stock and lead times, check TI.com and authorized distributors.
- If the TPS7B7702QPWPRQ1 is not immediately available, consider evaluating other members of the TPS7B770x‑Q1 family with compatible functionality and the same PWP package footprint; verify electrical and pin‑level compatibility against the datasheet before substitution.
- Request notifications on TI.com for stock updates, and consider buffer stock for programs with SOP and EOP ramp overlap.
How it fits into an automotive power tree
The dual‑channel structure of the TPS7B7702QPWPRQ1 suits architectures where a pre‑regulator (e.g., a buck converter) first drops the battery line, and the LDO then cleans post‑regulation rails for sensitive loads. Using a single device for two rails simplifies qualification and reduces supplier management overhead. The adjustable range up to 20 V broadens reuse across platforms and regional variants with different load needs.
Because specific parameters such as dropout voltage, PSRR, noise, and enable/diagnostic features are not specified here, always validate thermal and performance margins with the datasheet and lab characterization, especially across cold‑crank, load‑dump, and temperature extremes typical of automotive duty cycles.
