Summary of INFINEON’S TLS715B0NA LDO REGULATOR USES “FLIP-CHIP” TECHNOLOGY TO DIFFUSE HEAT
Infineon’s TLS715B0NA V50 OPTIREG is a 5 V low-dropout linear regulator delivering up to 150 mA with ±2% accuracy. It accepts 4–40 V input, has a typical quiescent current of 36 μA, very low dropout (≈180 mV at 100 mA), and requires only a 1 μF output capacitor. Features include enable, overtemperature shutdown, current limiting, -40°C to 150°C operation, RoHS compliance, and AEC qualification. Flip-chip packaging (TSNP-7-8, 2.0×2.0 mm) reduces footprint by >60% versus TSON-10 while maintaining thermal performance.
Parts used in the TLS715B0NA V50 – OPTIREG Linear Voltage Regulator Project:
- TLS715B0NA V50 OPTIREG linear voltage regulator (5 V output)
- Input voltage source (4.0 V to 40 V)
- Output capacitor, 1 μF (stable requirement)
- PCB for TSNP-7-8 package footprint (2.0 mm x 2.0 mm)
- Optional enable control signal
- Thermal management via PCB layout (flip-chip thermal path)
- Protection circuits as provided: overtemperature shutdown and output current limitation
TLS715B0NA V50 – OPTIREG™ Linear Voltage Regulator is a low dropout linear voltage regulator for load current up to 150 mA. An input voltage of up to 40 V is regulated to VQ,nom = 5 V with ±2 % precision. The TLS715B0, with a typical quiescent current of 36 μA, is the ideal solution for systems requiring very low operating current, such as those permanently connected to the battery.

What Are Flip-Chips?
With flip-chip technology, the ICs are installed upside down in the package. With the heated part of the IC facing the bottom of the package and being closer to the PCB, thermal inductance can be improved by a factor between 2 and 3. The higher power density enables a significantly smaller footprint than conventional package technologies.
The footprint of Infineon’s new linear voltage regulator (TSNP-7-8 package, 2.0 mm x 2.0 mm) is more than 60 percent smaller than that of an established reference product (TSON-10 package, 3.3 mm x 3.3 mm) while the thermal resistance stays the same. This makes the new device particularly suitable for applications with very limited board space, such as radar and cameras. The OPTIREG TLS715B0NAV50 provides 5 V with a maximum output current capability of 150 mA.
