Product details
Overview
IFX25001TS V85 from Infineon Technologies is a linear voltage regulator delivering fixed 8.5 V output at up to 400 mA, housed in a TO-220-3 package with integrated thermal shutdown and current limiting. It serves as a primary post-regulation stage in automotive body control modules requiring stable low-noise supply for microcontroller I/O rails and sensor interfaces.
For engineers reviewing the IFX25001TS V85 datasheet, IFX25001TS V85 pinout, IFX25001TS V85 application, or IFX25001TS V85 equivalent, key selection criteria include dropout voltage at 400 mA, load regulation over temperature, short-circuit behavior, and compatibility with 12 V nominal automotive battery input under cold-crank conditions.
Technical Context
This device operates as a monolithic NPN-based linear regulator with internal bandgap reference, error amplifier, and Darlington pass transistor. Its architecture supports operation from 5.5 V to 40 V input while maintaining ±2 % output voltage accuracy across -40 °C to +150 °C junction temperature.
Thermal protection activates at TJ ≥ 175 °C with automatic hysteresis recovery, and current limit is set at 600 mA typical with foldback characteristic during sustained overload. No external compensation components are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 8.5 V ±2 % (ensures compatible logic-level biasing for 8-bit MCUs and LIN transceivers) |
| Max Output Current | 400 mA continuous (supports dual CAN/LIN node power with margin) |
| Input Voltage Range | 5.5 V to 40 V (covers automotive battery range including load dump transients) |
| Dropout Voltage | 1.3 V at 400 mA (enables regulation down to 9.8 V input during cranking) |
| Load Regulation | ±0.5 % (0–400 mA load change; critical for analog sensor reference stability) |
| Quiescent Current | 12 mA typical (low enough for always-on domains without excessive standby drain) |
Pinout & Package
TO-220-3 package with vertical mounting orientation, tab connected to GND for thermal conduction and EMI shielding. Pin 1 = Input, Pin 2 = Ground, Pin 3 = Output.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IN) | Unregulated input supply | Accepts 5.5–40 V; requires ≥10 µF ceramic input capacitor for stability |
| Pin 2 (GND) | Reference and thermal return | Connected to heatsink; forms common return for feedback and protection circuitry |
| Pin 3 (OUT) | Regulated output | Delivers 8.5 V ±2 %; requires ≥22 µF low-ESR output capacitor for transient response |
Key Features
| Feature | Design Value |
|---|---|
| Integrated thermal shutdown | Activates at 175 °C junction temperature with 15 °C hysteresis for safe auto-recovery |
| Short-circuit protection | Foldback current limiting reduces power dissipation during output-to-ground fault |
| Wide input voltage range | Supports direct connection to automotive battery rail without pre-regulator |
| No external compensation | Stable with standard ceramic output capacitors; eliminates BOM and layout overhead |

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, wider temp range (−40 to +175 °C) | Requires level-shifting for 8.5 V–dependent peripherals | Select if system uses 5 V logic and needs higher current headroom |
| IFX25002TS V85 | Same package and pinout; adds enable input and reverse-battery protection | Enables controlled power sequencing and protects against installation errors | Choose when system-level safety mandates EN control or reverse polarity immunity |
Compared with TLE4275G V33 and IFX25002TS V85, the IFX25001TS V85 offers optimized cost and footprint for fixed 8.5 V applications without enable or reverse-battery requirements, simplifying design where those features are unused.

FAQ
What is the minimum input voltage required for regulation at full load?
The IFX25001TS V85 maintains regulation down to 9.8 V input at 400 mA load due to its 1.3 V dropout voltage. Below this threshold, output voltage drops linearly with input; operation below 5.5 V is not functional per datasheet limits.
Does this regulator require an external capacitor on the output pin?
Yes - a minimum 22 µF low-ESR ceramic or tantalum capacitor is required on the output pin for stability and transient response. The device is not stable with only bulk electrolytic capacitance; ESR must be ≤100 mΩ.
Is the IFX25001TS V85 qualified for automotive use?
Yes - it is AEC-Q100 qualified Grade 0 (−40 °C to +150 °C), with built-in reverse-polarity protection up to −18 V, load-dump immunity per ISO 7637-2 Pulse 5a, and certified for use in body control and comfort systems.
Can the output voltage be adjusted externally?
No - the IFX25001TS V85 provides a factory-trimmed fixed 8.5 V output. There is no feedback pin or external resistor network option; voltage adjustment is not supported by design or datasheet.
