Product details
Overview
TLE42764DVATMA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering a fixed 5-V ±2% output at up to 400 mA, featuring enable control, reverse polarity protection, overtemperature shutdown, and output current limiting. It operates from 5.5 V to 40 V input, supports automotive-grade operation from −40°C to +150°C, and consumes <10 µA in shutdown mode - ideal for always-on vehicle body electronics such as door modules and lighting controllers.
For engineers reviewing the TLE42764DVATMA1 datasheet, TLE42764DVATMA1 pinout, TLE42764DVATMA1 application, or TLE42764DVATMA1 equivalent, key selection criteria include dropout voltage under load, quiescent current in standby, thermal resistance of PG-TO252-5 package, AEC-Q100 qualification status, and compatibility with ceramic output capacitors ≥22 µF.
Technical Context
The TLE42764DVATMA1 implements a bandgap-referenced control amplifier driving a pass transistor with integrated saturation control and protection circuitry. Its architecture includes dedicated EN input with internal pull-down, GND-connected heat slug, and VA pin left unconnected (n.c.) in fixed-output variants like this one.
It delivers regulated 5-V output across wide input range (5.5–40 V) while maintaining stability with 22 µF ceramic output capacitor (ESR ≤3 Ω at 10 kHz). Protection functions - overcurrent limiting, thermal shutdown, and reverse polarity handling - operate autonomously without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5 V ±2% - ensures stable MCU/ASIC supply within automotive voltage tolerance bands |
| Max output current | 400 mA - sufficient for powering multiple sensors and logic ICs in distributed ECUs |
| Quiescent current | <10 µA in shutdown - enables permanent battery connection without excessive drain |
| Dropout voltage | Typ. 300 mV @ 400 mA - allows regulation down to 5.3 V input, critical for cold-crank scenarios |
| Operating temperature | −40°C to +150°C junction - qualified for under-hood and transmission control applications |
| Input voltage range | 5.5 V to 40 V - covers 12 V and 24 V automotive systems including load dump transients |
| AEC-Q100 grade | Qualified per Grade 1 (−40°C to +125°C ambient) and extended temp validation to +150°C |
Pinout & Package
Package: PG-TO252-5 (D-Pak), thermally enhanced with exposed GND-connected heat slug. Mounting requires soldering the slug to PCB copper area for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: I | Input voltage supply | Connect directly to bulk capacitor; must be decoupled with ceramic cap at IC pad |
| 2: EN | Enable control input | Active-high logic; internal pull-down ensures default OFF state during power-up |
| 3: GND | Ground reference and thermal path | Internally tied to heat slug; must be connected to large PCB GND plane for thermal management |
| 4: n.c. | No-connect terminal | Not bonded internally; may be left floating or tied to GND for mechanical stability |
| 5: Q | Regulated output | Requires local 22 µF ceramic capacitor with ESR ≤3 Ω (10 kHz); placement critical for stability |
Key Features
| Feature | Design Value |
|---|---|
| Reverse polarity protection | Withstands −42 V input without damage - eliminates need for external series diode in battery-reversal-prone locations |
| Overtemperature shutdown | Auto-recovery after cooldown - prevents latch-up during transient overload or poor heatsinking |
| Output current limitation | Peak limit ~600 mA with foldback - protects against sustained short-circuit without external fuse |
| Green product compliance | RoHS-compliant, halogen-free, lead-free - meets global automotive environmental requirements |
| Low dropout at full load | 300 mV max @ 400 mA - enables operation during 6 V cold-crank events in 12 V systems |
Applications
| Body Control Module (BCM) | LED Headlamp Driver Supply |
|---|---|
|

IC Role / Device Role / Timing Role: Low-quiescent backup regulator powered directly from vehicle battery. Use Value: Draws only 35 µA typical active current and <10 µA in EN-disabled state - extends parasitic drain budget. |
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 |
|---|---|---|---|
| NCP1117ST50T3G | Fixed 5-V output, 1 A rating, no EN pin, not AEC-Q100 qualified | Lacks enable control and automotive qualification; suitable only for non-safety industrial use | Select when higher current and cost sensitivity outweigh automotive compliance needs |
| TLV73350PDBVR | 5-V fixed, 300 mA, 45 µA IQ, no reverse polarity or load dump protection | Lower thermal robustness (−40°C to +125°C), no integrated fault protections | Choose for space-constrained consumer-grade designs where automotive stress immunity is unnecessary |
Compared with NCP1117ST50T3G and TLV73350PDBVR, the TLE42764DVATMA1 uniquely combines AEC-Q100 qualification, reverse polarity tolerance, enable control, and 150°C operation - making it the only option validated for direct battery connection in harsh automotive environments.

FAQ
Is TLE42764DVATMA1 pin-compatible with other TLE42764 variants?
No - TLE42764DVATMA1 uses PG-TO252-5 package with 5 pins, while TLE42764EV50 (SSOP-14) and TLE42764GV50 (TO263-5) have different pin counts, layouts, and thermal pads. Pin mapping differs significantly; board redesign is required for substitution.
What is the minimum output capacitance required for stability?
The datasheet specifies a minimum 22 µF ceramic capacitor at the Q pin with ESR ≤3 Ω measured at 10 kHz. Using lower capacitance or higher ESR risks oscillation, especially under dynamic load conditions common in automotive sensor interfaces.
Does TLE42764DVATMA1 require an external voltage divider for 5-V output?
No - the "DV" suffix denotes fixed 5-V output version; the VA pin is not connected internally and must be left floating or tied to GND. External resistors are only needed for adjustable versions (e.g., TLE42764DV).
Can TLE42764DVATMA1 survive load dump transients?
Yes - it withstands input voltages up to +45 V per absolute maximum ratings and includes internal protection against load dump-induced overstress. However, system-level TVS clamping is still recommended for sustained 40 V+ events per ISO 7637-2 Pulse 5a.
