Product details
Overview
IFX25001TSV50AKSA1 from Infineon Technologies is a linear voltage regulator delivering fixed 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, industrial PLC I/O power rails, and low-noise sensor supply circuits.
For engineers reviewing the IFX25001TSV50AKSA1 datasheet, IFX25001TSV50AKSA1 pinout, IFX25001TSV50AKSA1 application, or IFX25001TSV50AKSA1 equivalent, key selection criteria include dropout voltage at 400 mA, load regulation over temperature, short-circuit robustness, and AEC-Q100 qualification status for automotive deployment.
Technical Context
This device implements a monolithic bipolar linear regulator architecture with internal bandgap reference, error amplifier, and Darlington pass transistor. It features active current limiting that holds output current at ~550 mA during overload and thermal foldback that reduces current above 150 °C junction temperature.
Designed for automotive environments, it meets AEC-Q100 Grade 2 (−40 °C to +105 °C ambient) and supports input voltages from 5.5 V to 45 V DC. The regulator operates without external compensation and maintains stability with ceramic or tantalum output capacitors ≥10 µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2%, stable under 10–400 mA load and −40 °C to +125 °C junction temperature. |
| Max Output Current | 400 mA continuous; current limit activates at ~550 mA to protect internal pass element. |
| Dropout Voltage | Typ. 0.55 V at 400 mA, enabling operation with 5.55 V minimum input for full regulation. |
| Input Voltage Range | 5.5 V to 45 V DC - supports 12 V and 24 V automotive battery systems with load dump tolerance. |
| Thermal Shutdown | Activates at TJ ≥ 170 °C; hysteresis resets regulation at ~150 °C. |
| Quiescent Current | Typ. 12 mA at no load, rising to ~18 mA at 400 mA output - impacts standby power in always-on modules. |
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 connection | Accepts 5.5–45 V DC; requires local 100 nF ceramic decoupling within 5 mm of pin. |
| Pin 2 (GND) | Reference and return path | Internally tied to metal tab; must be soldered to ≥2 cm² copper pour for thermal compliance. |
| Pin 3 (OUT) | Regulated 5 V output | Supplies downstream logic/sensors; requires ≥10 µF low-ESR output capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 2 (−40 °C to +105 °C ambient), validated for automotive body electronics lifetime reliability. |
| Integrated current limiting | Clamps output at ~550 mA independent of input voltage - eliminates need for external foldback circuitry. |
| Thermal foldback protection | Reduces current limit progressively above 150 °C junction - prevents thermal runaway during sustained overload. |
| No external compensation required | Stable with ceramic or tantalum output caps ≥10 µF - simplifies layout and reduces BOM count. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-50CDCYR | Lower max input (15 V), lower current (800 mA), no AEC-Q100 rating, SOT-223 package. | Suitable for commercial-grade embedded systems only; lacks automotive transient and thermal robustness. | Select when cost and board space are critical and automotive qualification is not required. |
| TLE42754G | Same AEC-Q100 Grade 2, 5 V/400 mA, but includes reverse-polarity protection and higher PSRR (60 dB @ 1 kHz). | Better suited for direct-battery-connected nodes where polarity reversal risk exists. | Prefer when reverse-battery immunity is mandatory and PSRR >50 dB is needed for analog-sensitive designs. |
Compared with TLV1117-50CDCYR, IFX25001TSV50AKSA1 offers automotive qualification and 45 V input capability but larger TO-220 footprint; versus TLE42754G, it omits reverse-polarity protection but delivers identical thermal performance and lower quiescent current (12 mA vs. 15 mA).

FAQ
What is the maximum allowable input voltage for IFX25001TSV50AKSA1?
The absolute maximum input voltage is 45 V DC, verified per Infineon's datasheet Rev. 2.0 (2021). Operation above this level risks permanent damage to the internal pass transistor and bandgap reference. For 24 V systems with load dump transients, the device withstands ISO 7637-2 Pulse 5a (75 V/100 ms) only when used with external clamping diodes.
Does IFX25001TSV50AKSA1 require an external output capacitor?
Yes - a minimum 10 µF low-ESR capacitor (ceramic or tantalum) is mandatory at the output pin for stability, as confirmed in Section 7.3 of the official datasheet. Omitting it causes oscillation above 100 kHz and unregulated output voltage collapse under dynamic load steps.
Is the metal tab of the TO-220-3 package electrically connected?
Yes - the tab is internally bonded to Pin 2 (GND), as shown in the mechanical drawing (package code TSV50) and verified in the "Pin Configuration" section of the datasheet. This connection must be thermally and electrically tied to the PCB ground plane to meet thermal resistance specifications (RthJA = 50 K/W).
Can IFX25001TSV50AKSA1 be used in parallel for higher current?
No - the device lacks current-sharing capability or master-slave synchronization. Parallel connection causes unequal current distribution due to output voltage tolerance (±2%) and thermal drift mismatch, leading to premature failure of the unit with lowest dropout. Use a single higher-current regulator or discrete pass transistor solution instead.
