Product details
Overview
IFX27001TFVATMA1 from Infineon Technologies is a linear voltage regulator IC delivering adjustable positive output (1.25 V to 40 V), 1 A continuous output current, and ±1% initial output voltage accuracy in a TO-252-3 (DPAK) package. It operates with input voltages up to 45 V and features thermal shutdown and current limiting for industrial power rail stabilization.
For engineers reviewing the IFX27001TFVATMA1 datasheet, IFX27001TFVATMA1 pinout, IFX27001TFVATMA1 application, or IFX27001TFVATMA1 equivalent, key selection criteria include output adjustability range, dropout voltage at full load, thermal performance in DPAK, and integrated protection behavior under overload conditions.
Technical Context
This regulator uses an internal NPN pass transistor architecture with external resistor divider feedback for precise output voltage setting. It maintains regulation across input voltages from 3.5 V to 45 V and supports output currents up to 1 A with junction temperature limited to 150 °C.
Thermal shutdown activates at ~170 °C junction temperature, and foldback current limiting engages during short-circuit events. The device requires no external compensation and remains stable with ceramic or tantalum output capacitors ≥10 µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1 A continuous - supports single-rail microcontroller or sensor supply without external boost stages. |
| Output Voltage Range | 1.25 V to 40 V adjustable - set via two external resistors; enables flexible system-level voltage derivation. |
| Input Voltage Max | 45 V - compatible with unregulated 24 V industrial bus or automotive battery-supplied systems. |
| Initial Accuracy | ±1% at 25 °C - ensures tight tolerance on critical analog or reference rails without post-production trimming. |
| Dropout Voltage | 1.7 V at 1 A - allows operation with only 1.7 V headroom above regulated output, reducing power loss. |
| Thermal Shutdown | Activates at ~170 °C - protects silicon integrity during sustained overload or poor heatsinking. |
Pinout & Package
IFX27001TFVATMA1 is housed in a surface-mount TO-252-3 (DPAK) package with exposed thermal pad for enhanced PCB heat dissipation. Pin 1 is Input, Pin 2 is Ground, Pin 3 is Output.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IN) | Input voltage supply connection | Accepts unregulated DC input up to 45 V; requires local 10 µF ceramic bypass capacitor. |
| Pin 2 (GND) | Reference ground node | Common return path for input/output capacitors and feedback divider; must connect directly to thermal pad. |
| Pin 3 (OUT) | Regulated output terminal | Delivers adjustable positive voltage; connects to feedback resistor divider and load capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output via external resistors | Enables precise tailoring of output voltage without custom IC variants or trimming components. |
| Integrated thermal shutdown | Prevents permanent damage during ambient overheating or inadequate PCB copper area. |
| Current limiting with foldback | Reduces power dissipation during output shorts, lowering stress on pass transistor and PCB traces. |
| No external compensation required | Simplifies layout and reduces BOM count-stable with standard 10 µF output capacitance. |
Applications
| Industrial PLC I/O Module Power | Automotive Body Control Unit (BCU) |
|---|---|
Use Scenario: Providing stable 5 V or 3.3 V rail for isolated digital I/O drivers and ADC references in modular PLC backplanes. IC Role / Device Role / Timing Role: Primary linear regulator supplying low-noise, ripple-free power to analog front-end circuitry. Use Value: ±1% accuracy and low output noise ensure consistent ADC conversion and reliable optocoupler interface timing. | Use Scenario: Generating 5 V for microcontroller peripherals and CAN transceivers in non-safety-critical BCU subsystems. IC Role / Device Role / Timing Role: Local point-of-load regulator downstream of main DC/DC converter, handling transient load steps. Use Value: Foldback current limiting prevents latch-up during intermittent short circuits in wiring harnesses. |
| Test Equipment Auxiliary Supply | Medical Diagnostic Sensor Interface |
Use Scenario: Delivering clean 12 V bias to op-amp signal chains and precision DACs in benchtop multimeters. IC Role / Device Role / Timing Role: Low-noise linear regulator replacing switching alternatives where EMI must be minimized near sensitive measurement paths. Use Value: Dropout voltage ≤1.7 V allows use with 13.8 V intermediate rail, avoiding extra DC/DC stage and associated noise. | Use Scenario: Powering low-power analog front-end ICs (e.g., EEG amplifiers) requiring ultra-stable 2.5 V reference rails. IC Role / Device Role / Timing Role: Precision-adjustable regulator feeding high-impedance sensor bias networks and ADC reference inputs. Use Value: 1.25 V minimum output enables direct generation of common reference voltages without additional dividers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM317LD-TR | ±2% initial accuracy; higher 2.25 V dropout at 1 A; no thermal foldback. | Lacks integrated thermal foldback; less accurate output limits use in precision reference rails. | Choose when cost sensitivity outweighs accuracy and protection requirements. |
| LT1086CM-ADJ | ±1% accuracy; 1.5 V dropout at 1 A; requires ≥10 µF tantalum output cap for stability. | Lower dropout improves efficiency but mandates specific capacitor chemistry for stability. | Prefer when lower dropout is critical and tantalum capacitors are acceptable in design. |
Compared with LM317LD-TR and LT1086CM-ADJ, IFX27001TFVATMA1 offers tighter initial accuracy than the former and more robust capacitor compatibility than the latter-making it optimal for industrial designs needing both precision and layout flexibility.

FAQ
What is the minimum output voltage achievable with IFX27001TFVATMA1?
The IFX27001TFVATMA1 has a fixed internal reference voltage of 1.25 V, which sets the minimum output voltage when the ADJ pin is connected directly to the output. With proper resistor divider configuration, outputs down to exactly 1.25 V are supported-no external reference or trimming is needed to achieve this lower limit.
Does IFX27001TFVATMA1 require an external capacitor on the ADJ pin?
No, the IFX27001TFVATMA1 does not require an external capacitor on the ADJ pin. Its internal compensation eliminates the need for frequency-compensation capacitors, unlike legacy regulators such as the LM317. Stability is guaranteed with ≥10 µF output capacitance using ceramic, tantalum, or aluminum electrolytic types.
Can IFX27001TFVATMA1 operate with an input voltage of 5 V while regulating 3.3 V at 1 A?
Yes-input-to-output differential is 1.7 V, matching the specified dropout voltage at 1 A. At 5 V input and 3.3 V output, the device dissipates (5 − 3.3) × 1 = 1.7 W. With adequate PCB copper area (≥250 mm² thermal pad exposure), junction temperature remains within safe limits per datasheet derating curves.
Is the TO-252-3 package of IFX27001TFVATMA1 RoHS-compliant and lead-free?
Yes, IFX27001TFVATMA1 is manufactured in full compliance with RoHS Directive 2011/65/EU and is lead-free. The TO-252-3 package uses matte tin (Sn) plating on leads and conforms to JEDEC J-STD-020 moisture sensitivity level MSL3, supporting standard reflow profiles.
