Product details
Overview
TLE42764GV50ATMA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering a fixed 5.0 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 quiescent current <10 µA in shutdown mode via EN pin. It is AEC-Q100 qualified for automotive power supply rails including body control modules and sensor interfaces.
For engineers reviewing the TLE42764GV50ATMA1 datasheet, TLE42764GV50ATMA1 pinout, TLE42764GV50ATMA1 application, or TLE42764GV50ATMA1 equivalent, key selection criteria include its ±2% output accuracy, reverse polarity protection, overtemperature shutdown, adjustable/fixed variants, and PG-TO263-5 thermal performance in harsh environments.
Technical Context
The device integrates a bandgap reference, control amplifier, saturation control, and protection circuitry-including output current limiting and thermal shutdown-within a single silicon die. Its architecture supports both fixed (5.0 V) and adjustable output configurations via the VA pin on non-V50 variants.
Designed for permanent battery connection (VBAT), it features an enable input with internal pull-down, reverse polarity protection, and operation across -40°C to +150°C junction temperature. The PG-TO263-5 package provides low thermal resistance (RthJA = 35 K/W) when mounted on a 10 cm² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - ensures stable MCU/Sensor rail under load and temperature variation. |
| Max Output Current | 400 mA - sufficient for powering microcontrollers, CAN transceivers, and analog sensors. |
| Dropout Voltage | 0.5 V @ 400 mA - enables regulation down to 5.5 V input, critical for cold-crank automotive conditions. |
| Quiescent Current | <10 µA in shutdown - preserves battery life in always-on vehicle systems (e.g., alarm, telematics). |
| Operating Temp | -40°C to +150°C (Tj) - validated for under-hood and transmission-control applications. |
| Protection Features | Reverse polarity, overcurrent, overtemperature - eliminates need for external protection components. |
| Input Voltage Range | 5.5 V to 40 V - covers full automotive battery range including load dump transients. |
Pinout & Package
Package: PG-TO263-5 (D²PAK), thermally enhanced with exposed GND-connected heat slug. Mounting requires direct solder connection of heat slug to ≥10 cm² PCB copper area for RthJA ≤ 35 K/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: I | Input | High-side input terminal; must be decoupled directly at IC with ceramic capacitor (≥1 µF, X7R). |
| 2: EN | Enable Input | Active-high logic input; internal pull-down ensures default OFF state; drives <10 µA shutdown current. |
| 3: GND | Ground / Heat Slug | Reference node and thermal path; internally connected to exposed metal slug requiring PCB GND plane tie. |
| 4: n.c. | No Connect | Not bonded; may be left floating or tied to GND-no electrical function in TLE42764GV50ATMA1 variant. |
| 5: Q | Output | Regulated 5.0 V output; requires 22 µF low-ESR (≤3 Ω) output capacitor for stability per datasheet P_4.2.4/5. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 0 (-40°C to +150°C Tj) - certified for safety-critical automotive subsystems. |
| Reverse Polarity Protection | Withstands -42 V input - eliminates need for external series diode in battery-reversed fault scenarios. |
| Low Dropout Performance | 0.5 V @ 400 mA - maintains regulation during 6 V cold-crank events without brownout. |
| Integrated Thermal Shutdown | Triggers at ~175°C junction - protects against sustained overload without external sensing. |
| RoHS Compliant & Halogen-Free | Green Product per Infineon OPTIREG™ standard - meets EU ELV and automotive chemical compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout automotive voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Fixed 5.0 V, 300 mA max, 250 mV dropout, -40°C to +125°C | Limited to under-hood ambient ≤125°C; lacks reverse polarity protection | Preferred for cost-sensitive non-safety modules where thermal margin is adequate and reverse fault risk is mitigated externally. |
| TPS7B8250QDGNRQ1 | Fixed 5.0 V, 150 mA, 170 mV dropout, integrated watchdog timer, -40°C to +150°C | Lower current capacity; adds functional safety monitoring but no reverse polarity protection | Selected when ASIL-B diagnostics required and load current ≤150 mA; not suitable for 400 mA BCM rails. |
Compared with TLV73350PDBVR and TPS7B8250QDGNRQ1, the TLE42764GV50ATMA1 uniquely combines 400 mA drive, reverse polarity tolerance, and full Grade 0 thermal rating-making it the only option among the three qualified for high-current, high-ambient, fault-prone automotive loads.

FAQ
Is TLE42764GV50ATMA1 pin-compatible with earlier TLE42764 variants?
Yes-TLE42764GV50ATMA1 uses the PG-TO263-5 package with identical pinout (I-EN-GND-n.c.-Q) as other GV50/DV50 variants. Pin 4 (n.c.) remains unconnected and electrically inert; no redesign is needed when replacing TLE42764GV50 or TLE42764DV50 in existing layouts.
What is the minimum output capacitance required for stability?
The datasheet specifies a minimum 22 µF ceramic or tantalum output capacitor with ESR ≤3 Ω at 10 kHz. This value accounts for worst-case ±30% capacitance tolerance and ensures phase margin >45° across temperature and load conditions.
Does TLE42764GV50ATMA1 require an external voltage divider?
No-TLE42764GV50ATMA1 is the fixed 5.0 V version; the VA pin (Pin 4) is not connected internally and has no function. External resistors are only required for adjustable-output variants (e.g., TLE42764GV or TLE42764DV).
Can this regulator survive load dump transients?
It withstands input transients up to +45 V (absolute max), but sustained load dump (ISO 7637-2 Pulse 5a: 87 V/100 ms) exceeds this rating. System-level protection (e.g., TVS diode) is required upstream to clamp transients before they reach the TLE42764GV50ATMA1 input pin.
