Infineon TLS4120D0EPV33XUMA1 Automotive Voltage Regulator Overview for B2B Vehicle Safety Systems

The Infineon TLS4120D0EPV33XUMA1 is a rugged, automotive-grade linear voltage regulator??engineered for B2B applications demanding stable 3.3V power delivery, wide voltage tolerance, and extreme thermal resilience for Automotive Electronics. It targets safety-critical and comfort-focused vehicle systems: Advanced Driver Assistance Systems (ADAS) sensors (radar, lidar, cameras), in-vehicle infotainment (IVI) modules, and powertrain control units (PCUs). Key integrations include: fixed 3.3V output voltage (for low-voltage automotive components), 4.5V?C40V input range (handles 12V battery spikes/jump-starts), 93% peak efficiency (minimizes power loss), AEC-Q100 Grade 1 compliance (automotive reliability standard), SOT223 (Small Outline Transistor, 3-pin) surface-mount package, and -40??C to +150??C operating temperature??delivering consistent power to sensitive automotive electronics in harsh environments.

With 4.5V?C40V input range + AEC-Q100 Grade 1 compliance (tuned for automotive voltage variability and long-term durability), it balances three critical B2B needs: component protection (against voltage surges), space efficiency (fitting dense ECUs), and thermal resilience (surviving engine bay heat). As part of Infineon??s automotive IC lineup??a series trusted by 115,000+ automotive electronics engineers and ECU manufacturers??it meets strict quality benchmarks: AEC-Q100 Grade 1 (2,000+ hours of stress testing), ISO 26262 ASIL-B (functional safety for ADAS), RoHS 3, and UL 94V-0 (package flammability).

Senior engineers at a leading ADAS sensor manufacturer endorse it: ??This regulator powers our front-facing radar sensors. Its 40V input handles jump-start surges, and +150??C tolerance survives engine heat??we hit 99.97% sensor uptime and 98% automaker satisfaction.??

Advantages vs. Typical Alternatives

Compared to narrow-input automotive regulators (fail surges), low-grade AEC-Q100 regulators (fail extreme heat), and large-package regulators (no space for dense ECUs), this Infineon Voltage Regulator solves critical B2B pain points??backed by real automaker feedback:

1. Better Surge Protection Than Narrow-Input Regulators: Narrow-input (6V?C18V) regulators fail during 12V vehicle jump-starts (30V?C36V spikes), causing 14% of ADAS sensor failures and $900,000 yearly in warranty costs. The 4.5V?C40V range eliminates this. An ADAS engineer said: ??Our old 6V?C18V regulators broke 14% of radar sensors??this 40V model cuts failures to 1.2%. We saved $450k in warranties and retained a $4.5M contract with a global automaker, as their service teams hated surge-related repairs.??

2. Better Heat Tolerance Than Low-Grade AEC-Q100 Regulators: AEC-Q100 Grade 2 (max +125??C) regulators fail in engine bays (up to +140??C), causing 5% of IVI module failures and $200,000 yearly in automaker penalties. Grade 1 (+150??C) tolerance solves this. An IVI engineer shared: ??Our old Grade 2 regulators failed 5% of IVIs??this Grade 1 model fails 0.2%. We avoided $200k in penalties and won a $1.2M order for electric vehicle (EV) IVIs, as EV engine bays run hotter.??

3. Smaller Footprint Than Large-Package Regulators: DIP8 packages (9.5mm x 6.5mm) take up 35% more PCB space than SOT223 (6.5mm x 3.5mm), forcing powertrain ECUs to exceed engine bay size limits. The SOT223 enables miniaturization. A powertrain ECU engineer confirmed: ??Our old DIP8 ECUs were 40mm2??this SOT223 model is 26mm2. We launched a compact ECU for EVs and won a $2.8M contract, as EV makers need space for larger battery packs to boost range.??

We launched a compact ECU that fits all EV models we target and won a $2.8M contract, as EV makers prioritize space for larger batteries to boost range.??

Why is 93% efficiency important for HEV IVI systems?

HEV IVI systems rely on battery power??low-efficiency (85%) regulators waste 15% of power as heat, draining batteries faster and reducing range by 2 miles. 93% efficiency cuts waste to 7%, preserving range. An HEV engineer said: ??Our old 85% regulators shortened HEV range??this 93% model adds 1.8 miles per charge. A top automaker ordered 25,000 more IVI units, as their customers ranked range as a top priority, and we grew revenue by 22%.??

How does ??2% output accuracy protect ADAS lidar modules?
