Product details
Overview
TLE42502GHTSA1 from Infineon Technologies is a monolithic low-dropout voltage tracking regulator in PG-SCT595-5 package, designed to supply off-board automotive sensors with precise output voltage tracking (±5 mV at 1–10 mA), 50 mA output capability, and input voltage range of −42 V to +45 V. It integrates reverse polarity protection, overtemperature shutdown, and short-circuit proofing to ground and supply.
For engineers reviewing the TLE42502GHTSA1 datasheet, TLE42502GHTSA1 pinout, TLE42502GHTSA1 application, or TLE42502GHTSA1 equivalent, key selection criteria include tracking accuracy under load transients, thermal resistance (RthJA = 81 K/W on 2s2p board), standby current reduction via ADJ/EN logic control, and AEC-Q100 qualification for under-hood environments.
Technical Context
The TLE42502GHTSA1 implements a PNP-based tracking architecture where output voltage VQ is regulated by comparing it to an external reference applied at the ADJ/EN pin. Stability relies on meeting specified output capacitor requirements: ≥1 µF capacitance and ESR ≤3 Ω at 10 kHz.
It features integrated protection including current limiting (51–120 mA trip range), thermal shutdown activation at 151–200 °C junction temperature, and reverse polarity operation down to −42 V input. Standby mode reduces quiescent current when ADJ/EN is pulled low.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Tracking accuracy | ±5 mV (1–10 mA, 6–16 V input); enables precision biasing of analog sensor interfaces |
| Dropout voltage | 100–300 mV (at 10 mA, VADJ ≥ 4 V); allows regulation even with small VI–VQ margin |
| Input voltage range | −42 V to +45 V; withstands automotive load dump and reverse battery conditions |
| Junction temp. range | −40 °C to +150 °C; qualified per AEC-Q100 Grade 0 for engine compartment use |

Pinout & Package
Package: PG-SCT595-5 - thermally enhanced 5-pin SMD package with dual GND pins (Pins 2 & 5) internally connected and optimized for PCB heatsinking (RthJSP = 30 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ADJ/EN | Combined adjust reference and enable input; high = active regulation, low = standby; accepts 2.5–36 V reference |
| 2 | GND | Primary ground reference; internally tied to Pin 5; must connect to PCB heatsink area |
| 3 | I | Main supply input; supports −42 V to +45 V; requires local ceramic decoupling capacitor |
| 4 | Q | Tracker output; delivers up to 50 mA; requires ≥1 µF ceramic cap with ESR ≤3 Ω at 10 kHz |
| 5 | GND | Secondary ground terminal; internally connected to Pin 2; enhances thermal conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout tracking | 100 mV min dropout enables stable 5 V output from 5.1 V input in cold-cranking scenarios |
| Integrated reverse polarity protection | Operates safely with −42 V input without external diode; eliminates discrete protection components |
| Stable with ceramic output caps | Validated for ≥1 µF X7R/X5R ceramics (ESR ≤3 Ω), reducing BOM count vs. tantalum solutions |
| Adjustable output via external reference | Output tracks any 2.5–36 V reference applied to ADJ/EN-no internal feedback resistors required |
| AEC-Q100 qualified | Qualified to Grade 0 (−40 °C to +150 °C) with full reliability testing per automotive standards |
Applications
| Engine Coolant Temperature Sensor Supply | ABS Wheel Speed Sensor Bias |
|---|---|
|
Use Scenario: Powers NTC-based coolant temperature sensor in direct contact with engine block under thermal cycling. IC Role / Device Role / Timing Role: Voltage tracker supplying stable bias to sensor bridge while rejecting battery ripple and load-dump transients. Use Value: ±5 mV tracking accuracy ensures <0.1% gain error in sensor signal chain across −40 °C to +150 °C ambient. |
Use Scenario: Supplies Hall-effect wheel speed sensor mounted near brake rotor with high EMI exposure. IC Role / Device Role / Timing Role: Regulated power source with reverse polarity and short-circuit protection in harsh chassis environment. Use Value: −42 V to +45 V input tolerance prevents failure during jump-start or alternator surge events. |
| Transmission Oil Pressure Sensor Interface | Exhaust Gas Oxygen Sensor Heater Control |
|
Use Scenario: Provides regulated voltage to piezoresistive oil pressure sensor inside transmission housing. IC Role / Device Role / Timing Role: Low-noise tracking regulator with PSRR >48 dB at 100 Hz, minimizing supply-induced offset drift.

Use Value: Output short-circuit proofing to both ground and supply avoids latch-up during heater open-circuit faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage tracking regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV71718PDQNR | Fixed 1.8 V output; no tracking capability; 150 mA IOUT; max VIN = 5.5 V | Only suitable for low-voltage, fixed-output systems (e.g., MCU peripherals); not for automotive sensor biasing | Select only if system uses fixed 1.8 V rail and operates below 5.5 V input-cannot replace TLE42502GHTSA1 in tracking or high-voltage roles |
| MAX1725EUK+T | Fixed 3.3 V output; 250 mA IOUT; no reverse polarity or load-dump protection; max VIN = 28 V | Lacks AEC-Q100 qualification and automotive-grade fault protection; intended for industrial/commercial use | Consider only for non-automotive applications requiring higher current but tolerating reduced ruggedness and no reverse-battery support |
Compared with TLV71718PDQNR and MAX1725EUK+T, the TLE42502GHTSA1 uniquely combines adjustable tracking, −42 V to +45 V operation, AEC-Q100 Grade 0 qualification, and integrated reverse-polarity/short-circuit protection-making it irreplaceable for off-board automotive sensor supplies.

FAQ
What is the minimum output capacitor value required for stable operation?
The TLE42502GHTSA1 requires a minimum 1 µF ceramic output capacitor with ESR ≤3 Ω at 10 kHz. This value accounts for worst-case ±30% capacitance tolerance and ensures loop stability across temperature and load variations. X7R or X5R dielectrics are recommended.
How does the ADJ/EN pin function in tracking versus enable modes?
The ADJ/EN pin serves dual roles: when held high (≥2.5 V), it acts as the tracking reference input-the output Q follows this voltage precisely; when pulled low (<0.3 V), it disables the regulator into ultra-low-quiescent-current standby mode. No external pull-up is needed.
Can the TLE42502GHTSA1 survive reverse battery connection?
Yes. The device is rated for −42 V input and includes integrated reverse polarity protection. During reverse connection, leakage current is limited to −10 mA (typical) at −16 V, preventing damage without external diodes or MOSFETs-verified per AEC-Q100 stress testing.
What thermal derating applies above 100 °C junction temperature?
No explicit derating curve is published, but overtemperature protection activates between 151–200 °C, reducing output current to limit further heating. Continuous operation above 150 °C violates absolute maximum ratings and accelerates parametric degradation-designs must maintain Tj ≤150 °C using the provided RthJA values.
