Product details
Overview
IFX25001TC V85 from Infineon Technologies is a linear voltage regulator delivering fixed 8.5 V output at up to 400 mA, housed in a TO-263-3 (D²PAK) thermally enhanced package. It features thermal shutdown, current limiting, and reverse-polarity protection, and is used in automotive body control modules for stable supply to microcontrollers and sensors.
For engineers reviewing the IFX25001TC V85 datasheet, IFX25001TC V85 pinout, IFX25001TC V85 application, or IFX25001TC V85 equivalent, key selection criteria include dropout voltage at 400 mA, thermal resistance in PCB-mounted D²PAK layout, load transient response under 100 mA step changes, and AEC-Q100 Grade 1 qualification status.
Technical Context
This device operates as a monolithic NPN-based linear regulator with internal bandgap reference and error amplifier. Its feedback network is trimmed to deliver precise 8.5 V ±2% over temperature and line variations, and it maintains regulation down to 9.5 V input at full load.
Designed for automotive environments, it integrates thermal foldback above 150 °C junction temperature and sustains short-circuit operation indefinitely with automatic recovery. The TO-263-3 package enables direct heatsinking to PCB copper planes for sustained 400 mA output at ambient ≤85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 8.5 V ±2% - ensures stable MCU core/sensor bias across -40 °C to +150 °C junction range |
| Max Output Current | 400 mA - supports dual low-power MCUs or one MCU plus CAN transceiver simultaneously |
| Dropout Voltage | 600 mV @ 400 mA - enables operation from 9.1 V battery during cold-crank conditions |
| Thermal Resistance (RθJA) | 40 °C/W - achievable with 250 mm² 2-oz copper pad, enabling full-load operation at 85 °C ambient |
| Quiescent Current | 12 mA - low enough to meet ISO 16750-2 sleep-mode leakage limits in always-on domains |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment ECUs |
Pinout & Package
TO-263-3 (D²PAK) package with exposed thermal pad soldered to PCB ground plane for heat dissipation. Pin 1 = Input, Pin 2 = Ground, Pin 3 = Output.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IN) | Unregulated input supply | Accepts 9.1–40 V DC; must be decoupled with ≥10 µF ceramic near pin |
| Pin 2 (GND) | Power and signal reference | Internally tied to thermal pad; requires low-inductance connection to PCB ground plane |
| Pin 3 (OUT) | Regulated output | Delivers 8.5 V to load; requires ≥22 µF low-ESR output capacitor for stability |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-polarity protection | Withstands −40 V input without damage - eliminates need for external series diode in battery-reverse scenarios |
| Thermal shutdown with hysteresis | Activates at 165 °C TJ, releases at 145 °C - prevents thermal runaway during sustained overload |
| Current limit foldback | Reduces short-circuit current to ~150 mA above 1.2× nominal limit - lowers power dissipation during fault |
| Load transient response | ±150 mV deviation for 100 mA step change (25 ns rise time) - maintains MCU reset margin during sensor activation |
Applications
| Body Control Module (BCM) | Door Module ECU |
|---|---|
Use Scenario: Powering 8-bit MCU, LIN transceiver, and window motor driver IC in vehicle door assembly. IC Role / Device Role / Timing Role: Primary 8.5 V system rail regulator supplying logic and interface circuitry. Use Value: Reverse-polarity tolerance avoids fuse replacement after battery jump-start errors; thermal foldback enables safe operation during motor stall events. | Use Scenario: Supplying interior lighting controller and mirror position IC in rear quarter panel module. IC Role / Device Role / Timing Role: Stable 8.5 V source for analog sensor interfaces and EEPROM-backed configuration storage.

Use Scenario: Regulating power to seat position memory MCU and H-bridge gate drivers. IC Role / Device Role / Timing Role: Main 8.5 V rail generator with integrated fault protection for motor actuation subsystems.

Use Value: Thermal resistance of 40 °C/W enables continuous 350 mA output on compact 4-layer roof module PCB. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4275G V33 | Fixed 5.0 V output, 500 mA rating, higher quiescent current (20 mA) | Requires external LDO or resistor divider for 8.5 V systems | Select only if 5 V rail suffices and higher IQ is acceptable |
| IFX25401TE V85 | Same 8.5 V output but TO-220-3 package, RθJA = 60 °C/W, no reverse-polarity protection | Limited to lower ambient or derated load in space-constrained modules | Choose when board-level reverse protection exists and thermal budget allows |
Compared with TLE4275G V33 and IFX25401TE V85, IFX25001TC V85 uniquely delivers 8.5 V precision, reverse-polarity resilience, and D²PAK thermal performance-making it optimal for compact, high-reliability automotive modules where input polarity risk and thermal density are design constraints.

FAQ
What is the minimum input voltage required for regulation at 400 mA?
The IFX25001TC V85 requires a minimum input voltage of 9.1 V to maintain 8.5 V output at 400 mA load, based on its 600 mV dropout specification. Below this, output voltage drops linearly with input; operation below 9.1 V is permissible only in unregulated or pre-regulated stages.
Does IFX25001TC V85 require an external output capacitor, and what type is recommended?
Yes, a minimum 22 µF low-ESR aluminum polymer or tantalum capacitor is required at the output for stability and transient response. Ceramic capacitors alone are insufficient due to ESR requirements; a 22 µF polymer cap with ≤50 mΩ ESR meets Infineon's design validation criteria per datasheet section 7.3.
Is the thermal pad on the TO-263-3 package electrically connected, and how should it be handled?
The exposed thermal pad is internally connected to Pin 2 (GND). It must be soldered to a dedicated PCB ground plane using ≥6 thermal vias (0.3 mm diameter) to inner ground layers. Floating or unconnected pads cause thermal resistance to exceed 40 °C/W and may trigger premature thermal shutdown.
Can IFX25001TC V85 be used in non-automotive applications such as industrial controllers?
Yes, it is qualified for industrial use with full electrical specifications guaranteed from −40 °C to +125 °C ambient. However, AEC-Q100 stress testing (e.g., HTOL, TC) provides added confidence for long-term reliability in harsh environments beyond standard industrial grade requirements.
