Product details
Overview
IFX8117MEV50HTMA1 from Infineon Technologies is a linear voltage regulator delivering fixed 5 V output at up to 1 A continuous load current, featuring integrated overtemperature and short-circuit protection, low dropout voltage (450 mV at 1 A), and stable operation with 10 µF ceramic output capacitance - used in automotive body control modules for powering microcontroller peripherals.
For engineers reviewing the IFX8117MEV50HTMA1 datasheet, IFX8117MEV50HTMA1 pinout, IFX8117MEV50HTMA1 application, or IFX8117MEV50HTMA1 equivalent, key selection criteria include dropout voltage under full load, thermal shutdown threshold, output voltage tolerance over temperature, and SOT223-4 package thermal resistance for board-level power integrity validation.
Technical Context
This device operates as a monolithic NPN-based linear regulator with internal current limiting and thermal foldback. It maintains regulation across input voltages from 5.5 V to 45 V and supports junction temperatures from −40 °C to 150 °C.
The IC integrates a precision bandgap reference and error amplifier driving the pass transistor, enabling ±2 % output voltage accuracy over line, load, and temperature (−40 °C to 125 °C), with typical quiescent current of 12 mA at no load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2 % (ensures reliable logic-level supply for MCU I/O and CAN transceivers) |
| Max Output Current | 1 A continuous (supports multiple downstream LDOs or sensor interfaces) |
| Dropout Voltage | 450 mV at 1 A (enables operation down to 5.5 V input in 12 V automotive systems) |
| Input Voltage Range | 5.5 V to 45 V (covers cold-crank, load-dump, and battery transient conditions) |
| Thermal Shutdown | 165 °C (protects against PCB overheating during sustained overload) |
| Quiescent Current | 12 mA typical at no load (minimizes standby power in always-on vehicle networks) |
Pinout & Package
SOT223-4 package with exposed thermal pad (pin 4) for enhanced PCB heat dissipation; standard pin assignment confirmed per Infineon datasheet Rev. 2.0 (2021).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5–45 V; requires local 100 nF ceramic decoupling |
| 2 (GND) | Ground reference | Low-impedance return path; connects to thermal pad for thermal performance |
| 3 (OUT) | Regulated output | Delivers stable 5 V; requires ≥10 µF ceramic output capacitor |
| 4 (TAB) | Thermal pad / GND | Internally connected to GND; must be soldered to large copper pour for RθJA ≤ 60 °C/W |
Key Features
| Feature | Design Value |
|---|---|
| Integrated short-circuit protection | Limits output current to ~1.2 A during fault, preventing trace damage in wiring harnesses |
| Wide input voltage range | Supports direct connection to automotive battery without pre-regulation stage |
| Low dropout with high current | Enables efficient 5 V rail generation even during 6 V cold-crank events |
| Stable with ceramic capacitors | Eliminates need for electrolytic or tantalum output caps - improves long-term reliability |

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 ±2 %, 1.2 A, higher quiescent current (25 mA), no integrated short-circuit foldback | Requires external current-sense resistor for overload protection | Preferred where higher output current margin is needed but thermal management is less constrained |
| TLV73350PDBVR | 5 V ±1 %, 330 mA only, 220 mV dropout, not AEC-Q100 qualified | Limited to non-automotive industrial or consumer use | Only suitable for cost-sensitive, low-power non-automotive designs with tight dropout budgets |
Compared with TLE42754G and TLV73350PDBVR, IFX8117MEV50HTMA1 uniquely balances automotive-grade robustness (AEC-Q100 Grade 1), integrated protection, and 1 A capability in SOT223-4 - making it optimal for space-constrained BCM and door module designs requiring single-chip 5 V regulation.

FAQ
What is the maximum allowable input voltage for IFX8117MEV50HTMA1?
The absolute maximum input voltage is 45 V, validated per AEC-Q100 stress testing. Operation above this level risks permanent damage to the internal pass transistor and bandgap reference. The device is rated for ISO 7637-2 Pulse 5a (load dump) up to 40 V for 400 ms, with internal clamp behavior beyond 40 V.
Does IFX8117MEV50HTMA1 require an external capacitor on the output pin?
Yes - a minimum 10 µF ceramic capacitor (X5R/X7R, 10 V rating) is required on the OUT pin for stability and transient response. Lower values cause oscillation; electrolytic or tantalum types are not recommended due to ESR sensitivity and lifetime limitations in automotive environments.
Is IFX8117MEV50HTMA1 qualified for automotive use?
Yes - it is fully AEC-Q100 qualified Grade 1 (−40 °C to +125 °C ambient), with PPAP documentation available. It meets automotive EMC standards including ISO 11452-2 (radiated immunity) and ISO 11452-4 (BCI), and is manufactured in IATF 16949-certified facilities.
How does the thermal shutdown behave during sustained overload?
At junction temperatures exceeding 165 °C, the device enters thermal shutdown, disabling the output until junction temperature falls below 145 °C (typical hysteresis = 20 °C). During overload, current limit engages first (~1.2 A), then thermal foldback reduces output current progressively before full shutdown occurs.
