Product details
Overview
IFX25001TS V10 from Infineon Technologies is a linear voltage regulator delivering fixed 10 V output with 400 mA continuous output current in a TO-220-3 package. It features thermal shutdown, short-circuit protection, and ±2% output voltage tolerance over temperature and load. Used in industrial power supplies and automotive body control modules requiring stable low-noise bias rails.
For engineers reviewing the IFX25001TS V10 datasheet, IFX25001TS V10 pinout, IFX25001TS V10 application, or IFX25001TS V10 equivalent, key selection criteria include dropout voltage at full load, thermal resistance in PCB-mounted configuration, line regulation performance across 12–28 V input range, and transient response to 100 mA step load changes.
Technical Context
This device operates as a monolithic NPN-based series pass regulator with internal current limiting and thermal foldback. Its reference circuit uses a bandgap voltage source trimmed for ±2% initial accuracy, and the error amplifier drives the pass transistor via integrated driver stage.
Designed for operation with input voltages up to 40 V, it maintains regulation down to 11.5 V input at 400 mA load (typical dropout = 1.5 V). The TO-220-3 package provides 50°C/W junction-to-case thermal resistance when mounted on 1-in² copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 10 V ±2% (guaranteed over -40°C to +150°C junction temp) |
| Max Output Current | 400 mA continuous (limited by thermal design; derates above 100°C ambient) |
| Input Voltage Range | 11.5 V to 40 V (minimum input for regulation at full load) |
| Dropout Voltage | 1.5 V typical at 400 mA (defines minimum headroom needed for regulation) |
| Line Regulation | 0.01%/V typical (output change per volt input variation at constant load) |
| Load Regulation | 0.2% typical (output change from no-load to full-load at fixed input) |
| Quiescent Current | 9 mA typical (supply current consumed when regulating, independent of load) |
Pinout & Package
Supplied in TO-220-3 package with exposed metal tab (connected to Pin 2), standard mounting hole, and vertical lead orientation. Thermal performance requires mechanical attachment of tab to heatsink or large copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Input) | VIN | Unregulated DC input supply connection; must be decoupled with ≥10 µF electrolytic capacitor |
| Pin 2 (Tab/GND) | Ground / Heat Sink | Electrical ground reference and primary thermal path; electrically connected to case |
| Pin 3 (Output) | VOUT | Regulated 10 V output; requires ≥1 µF ceramic capacitor for stability |
Key Features
| Feature | Design Value |
|---|---|
| Thermal shutdown protection | Activates at TJ ≥ 170°C with automatic recovery after cooldown |
| Short-circuit current limit | 450 mA typical foldback limit prevents damage during sustained output shorts |
| Low noise output | 40 µVRMS (10 Hz–100 kHz) enables use in analog sensor biasing without added filtering |
| Wide input voltage range | Supports direct connection to 12 V/24 V automotive batteries including load-dump transients up to 40 V |
| High PSRR | 60 dB at 120 Hz (rejects ripple from upstream switching converters) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL783CKTTR | Adjustable output (1.25–125 V), higher dropout (2 V @ 750 mA), TO-220-3 | Requires external resistor divider; not drop-in for fixed 10 V use | Select only if programmable output or higher voltage capability is required |
| LM317HVK/883 | Adjustable output, 1.5 A rating, higher quiescent current (7 mA vs 9 mA), TO-3 | Larger footprint and different thermal interface; requires two resistors for 10 V setup | Prefer for higher current needs where TO-3 mounting is acceptable |
Compared with TL783CKTTR and LM317HVK/883, IFX25001TS V10 offers guaranteed fixed 10 V output, lower dropout, and automotive-qualified reliability-making it optimal for space-constrained, thermally demanding 10 V rail generation without external components.

FAQ
What is the maximum allowable input voltage for IFX25001TS V10?
The absolute maximum rated input voltage is 40 V DC, verified per Infineon's official datasheet Rev. 1.2. Operation above this level risks permanent damage even for brief transients. For automotive applications, it withstands ISO 7637-2 Pulse 5a (75 V, 100 ms) only when used with appropriate external clamping circuitry such as TVS diodes.
Does IFX25001TS V10 require an output capacitor for stability?
Yes - a minimum 1 µF ceramic capacitor (X7R or better) is required between Pin 3 (VOUT) and Pin 2 (GND) for phase margin compliance. Instability (oscillation) occurs without it, especially under light loads. Larger values (e.g., 10 µF) improve transient response but are not mandatory for basic regulation.
Can IFX25001TS V10 be paralleled for higher current?
No - the device lacks current-sharing features like remote sensing or master-slave control. Paralleling causes unequal current distribution due to output voltage tolerance mismatch (±2%), leading to thermal runaway in one unit. For >400 mA, select a higher-current regulator or redesign with a switching pre-regulator.
Is the metal tab electrically isolated in TO-220-3 packaging?
No - the exposed metal tab is internally connected to Pin 2 (GND) and serves as both thermal conduction path and electrical ground node. Insulating hardware (e.g., shoulder washers) must be used if mounting to a non-grounded heatsink to avoid short circuits.
