Product details
Overview
TLE4286GNTSA1 from Infineon Technologies is a 5-V fixed-output low-dropout linear voltage regulator in PG-SCT-595-5 package, designed for automotive power supply rails. It delivers up to 15 mA output current, maintains ±4% output accuracy across -40 °C to 150 °C, and features an inhibit input enabling <1 µA standby current. Used in engine control units (ECUs) for sensor biasing and microcontroller auxiliary rail regulation.
For engineers reviewing the TLE4286GNTSA1 datasheet, TLE4286GNTSA1 pinout, TLE4286GNTSA1 application, or TLE4286GNTSA1 equivalent, key selection criteria include AEC-Q100 qualification, 6.2–42 V wide input range, thermal shutdown behavior, short-circuit protected 5 V output, and PG-SCT-595-5 footprint compatibility with space-constrained automotive modules.
Technical Context
The TLE4286GNTSA1 integrates a bandgap reference, error amplifier, pass transistor, and protection circuitry in a monolithic silicon design. Its inhibit logic enables full shutdown via TTL/CMOS-compatible input (VINH < 0.3 V for OFF), reducing quiescent current to ≤1 µA at Tj < 85 °C.
Thermal protection activates at junction temperatures exceeding 150 °C, disabling output until safe recovery. Output stability requires ≥1 µF ceramic capacitor with ESR ≤10 Ω, and dropout voltage remains ≤1.1 V at 10 mA load across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% (4.8–5.2 V over temp/load; ensures stable MCU I/O rail under battery transients) |
| Input Voltage Range | 6.2 V to 42 V (supports 12 V and 24 V automotive systems including cold-crank and load-dump conditions) |
| Max Output Current | 15 mA (sufficient for powering small ASICs, CAN transceivers, or analog sensors without external boost) |
| Quiescent Current | 60 µA typical in ON mode (minimizes parasitic drain on vehicle battery during sleep modes) |
| Standby Current | ≤1 µA at Tj < 85 °C (enables long-term ECU memory retention with ultra-low leakage) |
| Dropout Voltage | 0.8 V typ. at 10 mA (allows regulation down to 5.8 V input-critical during cranking) |
| Operating Temp | -40 °C to +150 °C (AEC-Q100 Grade 0 qualified for under-hood placement) |
Pinout & Package
Package: PG-SCT-595-5 - 5-pin thermally enhanced SMD package with exposed thermal pad (pin 5 internally connected to GND), optimized for high ambient temperature PCB layouts in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INH) | Inhibit control input | Active-high logic: ≥3.5 V enables regulation; ≤0.3 V forces shutdown & <1 µA current draw |
| 2 (GND) | Ground reference | Primary ground connection; internally tied to pin 5 for low-inductance return path |
| 3 (I) | Input voltage supply | Accepts 6.2–42 V unregulated input; must be decoupled near pin with ≥100 nF ceramic cap |
| 4 (Q) | Regulated 5 V output | Requires ≥1 µF output capacitor (ESR ≤10 Ω) for stability; drives loads ≤15 mA |
| 5 (GND) | Ground / thermal pad | Exposed thermal pad; electrically and thermally connected to pin 2-must be soldered to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 0 (-40 °C to +150 °C) compliance verified per stress test plan-enables direct use in safety-critical ECU subsystems |
| Short-circuit protected output | Current-limited foldback behavior prevents damage during sustained output shorts-no external fuse required |
| Overtemperature shutdown | Thermal latch disables output above 150 °C junction; auto-recovery after cooldown-prevents thermal runaway in sealed enclosures |
| Low EMI operation | No switching noise; fixed LDO architecture eliminates need for RF filtering in sensitive analog sensor domains |
Applications
| Engine Control Unit (ECU) Sensor Bias Rail | Body Control Module (BCM) Wake-Up Circuit |
|---|---|
Use Scenario: Powers oxygen sensor heater control IC and analog front-end in gasoline/diesel ECUs under wide battery voltage swings (6–16 V). IC Role / Device Role / Timing Role: Provides stable 5 V reference and bias for precision ADCs and op-amps during cranking and alternator ripple events.

IC Role / Device Role / Timing Role: Provides post-regulation for noise-sensitive analog video paths after primary DC/DC conversion. Use Value: Low 60 µA quiescent current and 10 Ω ESR-compatible output cap minimize heat generation in thermally constrained plastic housings. |
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 | Lower max input (5.5 V), higher output current (300 mA), no inhibit input, not AEC-Q100 qualified | Suitable only for non-automotive industrial or consumer 5 V point-of-load; lacks thermal/EMC robustness for under-hood use | Select only if system operates below 6 V and requires higher current without automotive qualification |
| TPS7B6750QPWPRQ1 | Higher IQ (120 µA typ.), same 42 V max input, AEC-Q100 Grade 1 (−40 °C to +125 °C), integrated reset output | Supports broader industrial temperature range but limited to 125 °C junction-unsuitable for under-hood >125 °C zones | Prefer when reset signaling is needed and ambient stays ≤125 °C; avoid for transmission/turbocharger proximity |
Compared with TLV73350PDBVR and TPS7B6750QPWPRQ1, the TLE4286GNTSA1 uniquely combines Grade 0 temperature rating, sub-1 µA standby, and inhibit-controlled shutdown-making it irreplaceable for high-reliability automotive modules requiring extended thermal margin and ultra-low sleep current.

FAQ
What is the minimum input voltage required for regulation?
The TLE4286GNTSA1 requires a minimum input voltage of 6.2 V to maintain 5 V output within specification. Below this threshold, output voltage drops linearly with input due to insufficient headroom for the pass element-verified across −40 °C to +150 °C per datasheet Table 3.
Can the output capacitor be omitted in low-current applications?
No. The datasheet mandates a minimum 1 µF output capacitor with ESR ≤10 Ω for stability, regardless of load current. Omitting it risks oscillation or overshoot during load transients-even at 1 mA-as confirmed by Figure 3 application circuit and stability analysis in Section 4.4.
How does the inhibit function behave during cold-start conditions?
When INH is pulled low (<0.3 V), the device enters standby with ≤1 µA current draw, independent of input voltage magnitude. During cold-start (low battery), this ensures zero additional load on the cranking battery-verified in Table 4 under "Quiescent current (stand-by)" test condition.
Is the PG-SCT-595-5 package lead-free and RoHS compliant?
Yes. The TLE4286GNTSA1 is marked "Green product (RoHS compliant)" in its official datasheet (Rev. 2.3, p.1), and Infineon's packaging documentation confirms PG-SCT-595-5 uses lead-free solderable terminations and halogen-free molding compound.
