Product details
Overview
TLE4264GHTMA1 from Infineon Technologies is a 5-V fixed-output, low-dropout linear voltage regulator in PG-SOT223-4 package, designed for automotive power supply rails. It delivers ≥120 mA output current with ±2% output voltage tolerance, 0.25 V typical dropout at 100 mA, and operates across 5.5–45 V input range-used to power microcontrollers, sensors, and CAN transceivers in engine control units.
For engineers reviewing the TLE4264GHTMA1 datasheet, TLE4264GHTMA1 pinout, TLE4264GHTMA1 application, or TLE4264GHTMA1 equivalent, key selection criteria include AEC-Q100 qualification, reverse-polarity protection, thermal shutdown behavior, PSRR of 54 dB at 100 Hz, and stability with ≥10 µF/≤10 Ω ESR output capacitor.
Technical Context
The TLE4264GHTMA1 integrates a bandgap reference, error amplifier, series pass transistor with saturation control, and thermal shutdown circuitry. Its internal architecture enables stable regulation under wide input voltage swings (5.5–45 V) while maintaining tight output accuracy (4.9–5.1 V) across load currents from 5 mA to 100 mA and junction temperatures from –40°C to +125°C.
Protection features include short-circuit proofing via current limiting (120–160 mA), overtemperature shutdown (Tj > 150°C), and reverse-polarity tolerance (–42 V). Input and output capacitors are externally required: Ci with ~1 Ω damping resistor, and CQ ≥10 µF with ESR ≤10 Ω for loop stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5.0 V ±2% (4.9–5.1 V); ensures stable logic-level supply for automotive MCUs and peripherals. |
| Dropout voltage | 0.25 V typ. at 100 mA; enables operation down to 5.5 V input, critical for cold-crank battery conditions. |
| Max output current | 120 mA min.; sufficient for powering multiple low-power sensors or a single CAN transceiver. |
| PSRR | 54 dB at 100 Hz; suppresses alternator ripple and switching noise on vehicle battery rail. |
| Quiescent current | 9–15 mA at 100 mA load; balances efficiency and transient response in always-on modules. |
| Input voltage range | 5.5–45 V; supports 12 V and 24 V automotive systems including load dump (40 V surge). |
| Thermal shutdown | Activates at Tj = 150°C; prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
Package: PG-SOT223-4 (lead-free, RoHS-compliant), with exposed thermal pad connected to Pin 2/4 (GND) for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VI) | Input voltage | Accepts 5.5–45 V supply; must be decoupled directly to GND with ceramic capacitor. |
| 2, 4 (GND) | Ground reference | Common return path and thermal connection; pins 2 and 4 are internally tied and must both connect to PCB ground plane. |
| 3 (VQ) | Regulated 5-V output | Delivers stabilized 5 V; requires ≥10 µF output capacitor with ESR ≤10 Ω for stability across temperature. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 1 (–40°C to +125°C Tj) validation ensures reliability in engine bay and transmission control modules. |
| Reverse polarity protection | Withstands –42 V input; eliminates need for external series diode in battery-connected applications. |
| Short-circuit proof | Current-limited to 120–160 mA; sustains indefinite output short without latch-up or damage. |
| Low quiescent current | 400 µA at 1 mA load; enables ultra-low-power sleep modes in body control modules. |
| Green product | RoHS-compliant, halogen-free, and lead-free per JEDEC J-STD-609; meets global automotive environmental mandates. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
|
Use Scenario: Powering 5-V microcontroller core, EEPROM, and analog sensor interfaces in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Primary 5-V LDO supplying critical safety-relevant logic and ADC reference. Use Value: ±2% output tolerance and 54 dB PSRR ensure accurate sensor readings and deterministic MCU timing during cranking and load dump events. |

Use Value: 400 µA quiescent current minimizes battery drain during vehicle rest; reverse-polarity tolerance protects against service miswiring. |
| Transmission Control Module (TCM) | CAN Node Power Supply |
|
Use Scenario: Regulating 5-V supply for solenoid driver ICs and position sensor signal conditioning in automatic transmissions. IC Role / Device Role / Timing Role: High-reliability post-regulator after DC-DC converter, delivering clean 5 V to analog front-ends. Use Value: Dropout of 0.25 V allows operation during 6.5 V battery sag; thermal shutdown prevents failure under prolonged high-temperature gear shifting. |
Use Scenario: Providing isolated 5-V bias to standalone CAN transceivers (e.g., TJA1042, SN65HVD230) in distributed nodes. IC Role / Device Role / Timing Role: Dedicated point-of-load regulator ensuring stable VCC for CAN physical layer integrity. Use Value: Short-circuit proofing maintains bus availability even if transceiver fails short; 120 mA rating supports dual-CAN or CAN+LIN co-location. |
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 |
|---|---|---|---|
| NCP1117ST50T3G | Fixed 5 V, 1 A output, higher IQ (6 mA typ.), no AEC-Q100 qualification, SOT-223 package. | Targeted at industrial/commercial designs; lacks automotive-grade thermal and ESD robustness. | Use only in non-safety, non-automotive contexts where cost outweighs qualification requirements. |
| TLV73350PDBVR | 5 V, 330 mA, 60 µA IQ, but rated only to 40 V input and not AEC-Q100 qualified. | Suitable for infotainment or ADAS camera modules with lower voltage stress and tighter IQ budgets. | Select when ultra-low quiescent current is mandatory and automotive qualification is not required. |
Compared with NCP1117ST50T3G and TLV73350PDBVR, the TLE4264GHTMA1 uniquely combines AEC-Q100 Grade 1 qualification, reverse-polarity tolerance, and 45 V input capability-making it the only choice for under-hood power regulation where reliability under extreme electrical stress is non-negotiable.

FAQ
What is the minimum input voltage required for regulation?
The TLE4264GHTMA1 requires a minimum input voltage of 5.5 V to maintain 5.0 V output regulation. Below this threshold, the output drops linearly with input due to insufficient headroom for the pass element. This specification ensures reliable operation during automotive cold-crank conditions where battery voltage may dip to 6.0 V.
Can the TLE4264GHTMA1 drive a 100-mA load continuously at 125°C junction temperature?
Yes-the datasheet specifies 120 mA minimum output current across –40°C to +125°C junction temperature. However, continuous 100 mA operation at 125°C requires adequate PCB copper area (≥300 mm² heatsink) to maintain Rthj-a ≤85 K/W; otherwise, thermal shutdown will activate.
Is an input capacitor mandatory, and what value is recommended?
Yes-an input capacitor is mandatory for line transient suppression and stability. Infineon recommends a ceramic capacitor ≥1 µF placed directly between Pin 1 (VI) and Pin 2/4 (GND), with a ~1 Ω resistor in series to damp LC resonance between board inductance and Ci.
Does the TLE4264GHTMA1 require an external pull-up or pull-down on any pin?
No-no external biasing is required. All pins operate with defined internal logic: VI is high-impedance input, GND is hard-grounded, and VQ is actively regulated output. The device has no enable, reset, or flag pins; it powers up and regulates automatically upon valid input voltage application.
