Product details
Overview
IFX25001TC V10 from Infineon Technologies is a linear voltage regulator delivering fixed 10 V output with 400 mA continuous output current, thermal shutdown and current limiting protection, housed in TO-263-3 (D²PAK) package; used in automotive body control modules for stable MCU supply under load dump conditions.
For engineers reviewing the IFX25001TC V10 datasheet, IFX25001TC V10 pinout, IFX25001TC V10 application, or IFX25001TC V10 equivalent, key selection criteria include dropout voltage at 400 mA, load transient response under 100 mA/µs step, thermal resistance RthJA in PCB-mounted configuration, and AEC-Q100 Grade 1 qualification status.
Technical Context
This monolithic linear regulator integrates a precision bandgap reference, error amplifier, and power MOSFET in a single die. It operates with input voltages from 5.5 V to 45 V and maintains ±2% output voltage accuracy over temperature and line/load variations.
Designed for automotive environments, it features reverse battery protection down to –42 V, short-circuit foldback current limiting, and thermal shutdown with hysteresis. The device supports enable control via logic-level compatible EN pin and delivers <50 µVRMS output noise in 10 Hz–100 kHz bandwidth.
Key Specifications

| Dropout Voltage | Typ. 450 mV at 400 mA; enables operation with 10.5 V input in cold-crank scenarios |
| Quiescent Current | Typ. 250 µA in active mode; drops to <1 µA in shutdown (EN = low) |
| Thermal Shutdown | Activates at TJ ≥ 175°C with 15°C hysteresis; prevents permanent latch-up during overload |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE42754G | 5 V fixed output; 400 mA; same TO-263-3 package and AEC-Q100 Grade 1 rating | Not suitable where 10 V rail is required for downstream 10 V–5 V dual-LDO architectures | Select only if system architecture uses 5 V primary rail and no 10 V dependencies exist |
| IFX25002TE V50 | 5 V output version of same family; identical protection features, pinout, and thermal performance | Requires redesign of feedback network and output capacitor placement due to different output voltage | Use for drop-in replacement only when 5 V output is acceptable and board layout allows minor rework |
Compared with TLE42754G and IFX25002TE V50, IFX25001TC V10 uniquely provides 10 V output while retaining automotive-grade protection, enabling direct support of legacy 10 V sensor interfaces and dual-LDO topologies without external level-shifting.

FAQ
What is the maximum allowable input voltage for continuous operation?
The IFX25001TC V10 supports continuous operation up to 45 V input. It also survives transient load dump events up to 87 V for 100 ms per ISO 7637-2 Pulse 5a, without requiring external clamping components. This rating is validated under specified PCB thermal conditions with minimum copper area.
Does the device require an external capacitor on the EN pin for noise immunity?
No external capacitor is required on the EN pin. The internal enable circuit includes hysteresis and filtering sufficient for typical automotive harness noise. However, a 100 nF ceramic capacitor placed close to the EN pin is recommended when routing near high-dI/dt traces to prevent false triggering during EFT bursts.
Can IFX25001TC V10 be paralleled for higher current capability?
Paralleling is not supported. The device lacks current-sharing features such as current-sense outputs or master-slave synchronization. Attempting parallel operation may cause thermal imbalance and premature failure due to mismatched dropout voltages and thermal coefficients between units.
Is the thermal pad electrically isolated from other pins?
Yes, the exposed thermal pad is electrically isolated and must be connected to GND. It is not internally connected to any pin. Soldering the pad to a dedicated GND plane improves thermal performance and reduces RthJA by up to 22°C/W compared to non-connected pad configurations.
