Product details
Overview
TLE42672GATMA1 from Infineon Technologies is a 5 V, 400 mA automotive-grade linear post-regulator in PG-TO220-7 package with ±2% output voltage tolerance, 0.3–0.6 V dropout at full load, and integrated reset generator with adjustable delay. It delivers stable power to ECUs, body control modules, and sensor interfaces under harsh supply conditions up to 40 V input.
For engineers reviewing the TLE42672GATMA1 datasheet, TLE42672GATMA1 pinout, TLE42672GATMA1 application, or TLE42672GATMA1 equivalent, this device supports AEC-Q100 qualified designs requiring precise 5 V regulation, low standby current (≤10 µA), overvoltage protection to 60 V/400 ms, reverse polarity immunity, and self-holding logic via inhibit/hold inputs.
Technical Context
The TLE42672GATMA1 implements a bandgap-referenced linear regulator with saturation control to prevent pass transistor over-saturation across 5.5–40 V input range. Its internal control amplifier drives a buffered pass element to maintain 5 V output with ≤50 mV load regulation and 15–25 mV line regulation.
It integrates a dedicated reset generator with open-collector RO output, externally programmable delay via capacitor on D pin, and dual logic inputs (E2 inhibit, E6 hold) enabling latch-up-free enable sequencing without external components. Protection includes overtemperature shutdown, short-circuit proofing, and reverse polarity robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5.0 V ±2% - ensures compatibility with 5 V microcontrollers and CAN transceivers in automotive domains. |
| Max output current | 400 mA - sufficient for powering multiple ASICs or sensors in body electronics modules. |
| Dropout voltage | 0.3–0.6 V at 400 mA - enables operation down to 5.5 V input, supporting cold-crank scenarios. |
| Standby current | ≤10 µA at 25°C - minimizes battery drain during vehicle sleep mode. |
| Input voltage range | 5.5–40 V - covers full automotive battery range including load dump transients. |
| Overvoltage protection | 60 V for ≤400 ms - survives ISO 7637-2 pulse 5a without latch-off or damage. |
| Reset threshold | 1 V output detection - guarantees reliable system reset before brownout of downstream logic. |
| AEC-Q100 qualification | Grade 1 (−40°C to +125°C junction) - validated for engine bay and chassis-mounted applications. |
Pinout & Package
Package: PG-TO220-7 (thermally enhanced, exposed paddle soldered to PCB ground plane for RthJC = 6 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input | Main unregulated supply input; requires local ceramic decoupling to suppress high-frequency noise. |
| 2 (E2) | Inhibit | Active-high enable with 100 kΩ internal pull-down; asserts reset when pulled low. |
| 3 (RO) | Reset output | Open-collector signal indicating valid 5 V output; pulled up externally to monitor system health. |
| 4 (GND) | Ground | Power and signal reference; connected to exposed thermal paddle for thermal conduction. |
| 5 (D) | Reset delay | Connects to GND via timing capacitor to set reset timeout (e.g., 100 nF ≈ 100 ms). |
| 6 (E6) | Hold | Internal 50 kΩ pull-up to output; enables self-holding circuit after initial enable pulse. |
| 7 (Q) | Output | Regulated 5 V supply; requires 22 µF low-ESR capacitor (≤3 Ω) for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable reset delay | Capacitor-programmable (0.1–1000 ms typical) - eliminates need for external timer ICs in ECU boot sequencing. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA max output, 1.8 V min input, no reset or inhibit logic, SOT-23-5 package | Lacks automotive qualification, reset signaling, and high-voltage tolerance; suited for non-safety consumer modules | Select only for cost-sensitive, non-AEC-Q100 applications with <300 mA load and stable 5–6 V input. |
| TPS7B8750QKVURQ1 | 500 mA output, 3 V min input, integrated watchdog timer, wettable flank QFN package | Includes watchdog but no hold function; higher quiescent current (25 µA vs. 1 µA); requires external reset capacitor | Prefer when system-level watchdog supervision is required and thermal performance permits QFN mounting. |

FAQ
What is the minimum input voltage required for regulation?
The TLE42672GATMA1 requires a minimum input voltage of 5.5 V to maintain 5 V output regulation at full 400 mA load. Below this threshold, the output drops linearly with input due to insufficient headroom for the pass transistor. This specification enables reliable operation during automotive cold-crank events where battery voltage may dip to 5.5 V.
How is the reset delay time calculated from the external capacitor?
Reset delay (treset) is approximately 1.1 × Rint × CD, where Rint is the internal resistor (~1 MΩ) connected to pin D and CD is the capacitor value in farads. For example, a 100 nF capacitor yields ~110 ms delay. The exact relationship is confirmed in Figure 11 of the datasheet (Rev. 1.1, p.11) and validated across temperature.
Does the device require an output capacitor, and what are its specifications?
Yes - a minimum 22 µF low-ESR aluminum or tantalum capacitor (ESR ≤3 Ω) must be placed directly at pin 7 (Q) to ensure loop stability and transient response. Ceramic capacitors alone are insufficient due to their ultra-low ESR; a hybrid approach (e.g., 22 µF tantalum + 100 nF ceramic) is recommended per Section 5.2 of the datasheet.
Can the TLE42672GATMA1 be used in parallel for higher current?
No - the device lacks current-sharing features such as current-sense outputs or master/slave configuration pins. Parallel connection risks thermal runaway due to mismatched dropout voltages and is explicitly prohibited in the datasheet (Section 5.3). For >400 mA, select a higher-current regulator like TLE4274G or use a switching pre-regulator.
