Product details
Overview
TLE42764GVATMA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering a fixed 5-V ±2% output at up to 400 mA, with input voltage range 5.5–40 V, dropout voltage as low as 0.5 V at 400 mA, and enable-controlled shutdown drawing <10 µA. It features reverse polarity protection, overtemperature shutdown, and current limiting, and is qualified per AEC-Q100 for automotive body electronics, infotainment power rails, and always-on ECU modules.
For engineers reviewing the TLE42764GVATMA1 datasheet, TLE42764GVATMA1 pinout, TLE42764GVATMA1 application, or TLE42764GVATMA1 equivalent, key selection criteria include its 5-V fixed output precision, -40°C to +150°C operating range, PG-TO263-5 thermal performance, and enable-driven ultra-low quiescent current in standby mode.
Technical Context
The TLE42764GVATMA1 integrates a bandgap reference, control amplifier, and saturation-controlled pass transistor in a single die, with internal temperature sensing and current-limit circuitry that triggers foldback during overload. Its architecture supports stable regulation under wide input transients (e.g., load dump up to 40 V) while maintaining tight output tolerance across temperature and line/load variations.
Enable functionality uses an integrated pull-down resistor and logic-level compatible input (VIH ≥ 2.0 V, VIL ≤ 0.8 V), allowing direct microcontroller GPIO control without external biasing. The device's VA pin is internally disconnected in the GV50 variant, confirming fixed 5-V operation - no external feedback network required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - Ensures stable MCU core or sensor supply within automotive-grade accuracy limits |
| Max Output Current | 400 mA - Supports mid-power loads like CAN transceivers, display drivers, or small microcontrollers |
| Dropout Voltage | 0.5 V at 400 mA - Enables operation down to 5.5 V input, critical during cold-crank battery conditions |
| Quiescent Current | <10 µA in disable mode - Meets ISO 8859-3 "parking mode" current budget for always-connected modules |
| Operating Temp | -40°C to +150°C junction - Validated for under-hood placement near engine control units |
| Input Voltage Range | 5.5 V to 40 V - Withstands automotive load dump (ISO 7637-2 Pulse 5a) without external clamping |
| Protection Features | Reverse polarity, overtemperature shutdown, and current limiting - Eliminates need for discrete protection circuitry |
Pinout & Package
Package: PG-TO263-5 (D²PAK), thermally enhanced with exposed GND slug soldered to PCB copper pour for efficient heat dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: I | Input Supply | Primary VIN connection; requires local 100 nF ceramic capacitor directly to GND |
| 2: EN | Enable Control | Active-high logic input; internal pull-down ensures default OFF state on power-up |
| 3: GND | Ground Reference | Signal and power ground; internally bonded to exposed heat slug |
| 4: n.c. | No Connect | Not internally connected; may be left floating or tied to GND for mechanical stability |
| 5: Q | Regulated Output | 5-V output; requires ≥22 µF output capacitor with ESR ≤3 Ω (10 kHz) for stability |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 0 (-40°C to +150°C) qualification confirmed - enables use in safety-critical automotive subsystems |
| Reverse Polarity Protection | Withstands -42 V input without damage - eliminates need for external series diode in battery-reversed fault scenarios |
| Ultra-Low Standby Current | <10 µA when EN = low - extends battery life in telematics and alarm systems powered continuously from VBAT |
| Integrated Thermal Shutdown | Triggers at ~175°C junction and auto-recovers after cooldown - prevents latch-up during sustained overload |
| Fixed 5-V Output Accuracy | ±2% over full temp/load range - meets requirements for ADC references and digital logic supply rails |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA max output, 250 mV dropout at 300 mA, SOT-23-5 package, no reverse polarity protection | Limited to lower-power portable or non-automotive applications due to missing AEC-Q100 and reverse-voltage hardening | Select only for cost-sensitive consumer designs where automotive qualification and reverse protection are unnecessary |
| TPS7B8750QKVURQ1 | 500 mA output, 300 mV dropout at 500 mA, integrated watchdog timer, same AEC-Q100 Grade 1 rating | Supports functional safety monitoring but lacks reverse polarity protection and has higher quiescent current (25 µA) | Prefer when system-level ASIL-B compliance requires built-in fault detection, accepting trade-off in reverse-voltage robustness |
Compared with TLV73350PDBVR and TPS7B8750QKVURQ1, the TLE42764GVATMA1 uniquely combines AEC-Q100 Grade 0 operation, -42 V reverse withstand, and sub-10 µA disable current - making it optimal for harsh-environment always-on automotive nodes where protection and ultra-low standby power are non-negotiable.

FAQ
What is the maximum allowable input voltage for TLE42764GVATMA1?
The absolute maximum input voltage is 45 V, but the functional operating range is specified from 5.5 V to 40 V. Operation above 40 V is permissible only during transient events such as ISO 7637-2 Pulse 5a (load dump), which the device is designed to survive without external clamping components.
Does TLE42764GVATMA1 require an external feedback resistor network?
No. The 'GV50' suffix indicates a fixed 5-V output version; the VA pin is not connected internally and must be left unconnected or tied to GND. Only adjustable variants (e.g., TLE42764GV) require external resistors to set output voltage between 2.5 V and 20 V.
How is thermal performance managed in the PG-TO263-5 package?
The PG-TO263-5 package features an exposed GND slug thermally connected to the die. For optimal performance, the slug must be soldered to a minimum 200 mm² copper area on the PCB with ≥4 thermal vias to inner ground planes, achieving typical RθJA of 45°C/W under standard JEDEC 2S2P layout conditions.
Can TLE42764GVATMA1 be used in non-automotive applications?
Yes - its wide input range (5.5–40 V), -40°C to +150°C operation, and robust protection make it suitable for industrial PLC I/O modules, battery-powered test equipment, and railway signaling systems where reliability under electrical stress is critical.
