Product details
Overview
TLE42672GATMA2 from Infineon Technologies is a 5-V automotive-grade low-dropout linear voltage regulator in PG-TO220-7-4 package, delivering ≥400 mA output current with ±2% output voltage tolerance, input voltage range of 5.5–40 V, and integrated reset function with adjustable delay via external capacitor. It serves as primary power supply for ECUs, body control modules, and sensor interfaces requiring stable 5-V rail under harsh automotive conditions.
For engineers reviewing the TLE42672GATMA2 datasheet, TLE42672GATMA2 pinout, TLE42672GATMA2 application, or TLE42672GATMA2 equivalent, key selection criteria include its self-holding logic (E2/E6 dual enable), 1-V reset threshold, reverse polarity protection, overvoltage survival up to 60 V/400 ms, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE42672GATMA2 implements a bandgap-referenced control amplifier driving a series pass transistor with saturation control to prevent over-saturation across load currents. Its reset generator uses an external capacitor on pin D to set delay time, with fast discharge when output falls below 1 V reset threshold (VRT).
Turn-on/off logic combines two digital inputs: E2 (inhibit, active-high, 100 kΩ internal pull-down) and E6 (hold, active-low, 50 kΩ internal pull-up). Table 1 confirms self-holding behavior-device remains ON after E2 deactivates if E6 is held low, eliminating need for external latching circuitry.
Key Specifications

Pinout & Package
Package: PG-TO220-7-4 (thermally enhanced through-hole, rear-side GND tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input | Primary VIN connection; requires local ceramic decoupling to suppress line impedance resonance |
| 2 (E2) | Inhibit | Active-high enable with 100 kΩ internal pull-down; typically driven by ignition switch signal |
| 3 (RO) | Reset Output | Open-collector output referenced to GND; pulls low when VQ < 1 V, internally pulled up to VQ via 30 kΩ |
| 4 (GND) | Ground | Power and signal reference; connected directly to rear thermal pad for heat dissipation |
| 5 (D) | Reset Delay | Capacitor connection point for programmable reset timeout; charges at fixed ID current above VRT |
| 6 (E6) | Hold | Active-low hold input with 50 kΩ internal pull-up; sustains regulation after E2 removal for self-hold operation |
| 7 (Q) | 5-V Output | Regulated output; requires ≥22 μF/ESR ≤3 Ω output capacitor for loop stability across −40 °C to +150 °C |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5-V automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70750PDBVR | 300 mA max output, no reset output or hold logic, SOT-23-5 package | Lacks self-hold and programmable reset; suited only for non-critical, low-current loads | Select only if system uses MCU-based reset management and thermal environment stays <125 °C |
| TPS7B6950QDCYRQ1 | 250 mA output, integrated watchdog timer, 45 V max input, no E6 hold pin | Includes watchdog but omits dual-enable logic; requires external latch for ignition-off hold | Prefer when system-level watchdog supervision is mandatory and board space permits discrete hold circuit |
Compared with TLV70750PDBVR and TPS7B6950QDCYRQ1, the TLE42672GATMA2 uniquely integrates self-holding logic, 400 mA drive, and 1-V reset threshold-enabling simplified, robust ECU power architecture without added discretes or firmware overhead.

FAQ
What is the purpose of the E6 (Hold) pin?
The E6 pin provides active-low hold functionality: when pulled low, it maintains regulator output even after the E2 (Inhibit) signal goes low-enabling self-holding behavior without external latching components. This is used in body control modules to retain power during ignition-off states while preserving RAM contents and real-time clock operation.
Can the reset delay be adjusted, and how?
Yes-the reset delay is set by an external capacitor connected between pin D (Reset Delay) and GND. The internal current source charges this capacitor above the reset threshold voltage; delay time scales linearly with capacitance value. Typical values range from 100 nF (sub-millisecond) to 10 μF (hundreds of milliseconds), per Figure 5 in the datasheet.
Does the TLE42672GATMA2 require an input capacitor, and why?
Yes-an input capacitor (CI) is mandatory to damp resonant oscillations caused by PCB trace inductance interacting with CI. A ~1 Ω resistor in series with CI is recommended to critically damp this LC network. Without it, line transients can induce instability or false reset triggering during load-dump events.
Is the output capacitor ESR critical, and what is the limit?
Yes-the output capacitor must have ESR ≤3 Ω across −40 °C to +150 °C to ensure closed-loop stability. Stability is guaranteed only with ≥22 μF capacitance and this ESR limit; higher ESR risks oscillation or poor transient response during load steps typical in ECU power domains.
