Product details
Overview
TLE4267GATMA1 from Infineon is a 5 V low-dropout linear voltage regulator in PG-TO263-7 package, delivering ≥400 mA output current with ±2% output voltage tolerance, input voltage range of 5.5–40 V, and integrated overtemperature, short-circuit, reverse-polarity, and overvoltage (60 V/400 ms) protection. It serves as a primary power supply for automotive ECUs directly connected to the battery rail.
For engineers reviewing the TLE4267GATMA1 datasheet, TLE4267GATMA1 pinout, TLE4267GATMA1 application, or TLE4267GATMA1 equivalent, key selection criteria include reset delay adjustability via external capacitor, open-collector reset output with internal 30 kΩ pull-up, inhibit logic control, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE4267GATMA1 implements a bandgap-referenced control amplifier driving a pass transistor with saturation control and thermal shutdown circuitry. Its reset generator uses an external capacitor on the D pin to set delay time, while the RO pin provides open-collector reset signaling tied internally to the Q output via 30 kΩ.
It features dual enable logic: E2 (active-high inhibit with 100 kΩ internal pull-down) and E6 (hold function referenced to output voltage with 50 kΩ internal pull-up). The device operates across -40 °C to +150 °C junction temperature and supports stable regulation down to 1 V output during reset assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - ensures precise MCU/core logic supply within automotive voltage tolerance bands |
| Max Output Current | ≥400 mA - sufficient to power multiple downstream ICs including CAN transceivers and sensors |
| Input Voltage Range | 5.5 V to 40 V - accommodates cold-crank (5.5 V) and load-dump (40 V) conditions per ISO 7637-2 |
| Dropout Voltage | Typ. 0.5 V at 400 mA - enables regulation even during low-battery operation without dropout |
| Reset Threshold | 1.0 V output level - guarantees deterministic system reset before brownout-induced logic corruption |
| Overvoltage Protection | 60 V for ≤400 ms - survives ISO 7637-2 Pulse 5a load-dump transients without latch-off |
| Standby Current | <100 µA - minimizes quiescent drain on vehicle battery during sleep mode |
Pinout & Package
Package: PG-TO263-7 (TO-263-7), thermally enhanced surface-mount package with exposed die pad for improved heat dissipation; RthJC = 6 K/W enables high-current operation in compact automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input | Primary VIN connection; requires local 100 nF ceramic decoupling to GND at IC pin |
| 2 (E2) | Inhibit | Active-high enable; internal 100 kΩ pull-down ensures default OFF state at power-up |
| 3 (RO) | Reset Output | Open-collector signal; pulled up to Q via 30 kΩ internally-drives external reset logic or microcontroller nRST |
| 4 (GND) | Ground | Power ground reference; connected to rear thermal pad-must be soldered to large copper pour |
| 5 (D) | Reset Delay | Capacitor connection point; sets reset timeout (e.g., 100 nF ≈ 100 ms) per RC timing |
| 6 (E6) | Hold | Output-voltage referenced control; internal 50 kΩ pull-up to Q enables hold functionality during transient dips |
| 7 (Q) | 5 V Output | Regulated output; requires 22 µF low-ESR (≤3 Ω) bulk capacitor to stabilize loop response |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable Reset Delay | Externally set via capacitor on D pin-enables precise power-on sequencing alignment with MCU boot requirements |
| Open-Collector Reset Output | RO pin drives external logic without external pull-up-reduces BOM count and simplifies interface to diverse reset controllers |
| Reverse Polarity Protection | Withstands -42 V input-eliminates need for external series diode in battery-connected applications |
| AEC-Q100 Qualified | Grade 0 (-40 °C to +150 °C) qualification-validates reliability for engine control, transmission, and ADAS modules |
| Low Standby Current | <100 µA in inhibit mode-meets OEM requirements for <100 µA total ECU sleep current budgets |

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 |
|---|---|---|---|
| TLV73350PDBVR | 300 mA max output, no reset output, no overvoltage protection beyond 6 V | Not qualified to AEC-Q100; limited to infotainment or non-safety subsystems | Use only where output current ≤300 mA and fault protection is handled externally |
| TPS7B8750QKVURQ1 | 500 mA output, integrated watchdog timer, higher quiescent current (25 µA vs. <100 µA) | AEC-Q100 Grade 1 (−40 °C to +125 °C); lacks reverse polarity protection | Prefer when watchdog supervision is required and reverse battery risk is mitigated externally |
Compared with TLV73350PDBVR and TPS7B8750QKVURQ1, the TLE4267GATMA1 uniquely combines 400 mA output, full ISO 7637-2/16750-2 protection, AEC-Q100 Grade 0 rating, and programmable reset-all in a single PG-TO263-7 package-making it optimal for high-integrity power domains.

FAQ
What is the minimum input voltage required for regulation?
The TLE4267GATMA1 requires a minimum input voltage of 5.5 V to maintain 5 V output regulation at full load. Below this threshold, the device enters dropout mode and output voltage drops linearly with input. This specification aligns with ISO 16750-2 cold-crank test requirements for automotive electronics.
How is the reset delay time calculated from the external capacitor?
The reset delay time tdelay is determined by tdelay ≈ 1.1 × Rint × CD, where Rint is the internal resistor (~1 MΩ) and CD is the capacitor connected between D pin and GND. For example, a 100 nF capacitor yields ~110 ms delay, verified in Figure 13 of the datasheet Rev. 2.61.
Does the TLE4267GATMA1 require an external pull-up on the RO pin?
No. The RO pin is an open-collector output with an internal 30 kΩ pull-up resistor to the Q (5 V) output. An external pull-up is unnecessary unless a different voltage level (e.g., 3.3 V) or faster rise time is required-then a discrete resistor to the target rail may be added.
Can the TLE4267GATMA1 operate without the E2 inhibit pin connected?
Yes. Pin E2 has an internal 100 kΩ pull-down resistor, so leaving it unconnected defaults the device to enabled (ON) state. However, for systems requiring controlled startup sequencing, E2 should be actively driven high after power stabilization to prevent premature enablement during input ramp-up.
