Product details
Overview
TLE4250GHTSA1 from Infineon Technologies is a monolithic low-drop voltage tracker IC designed for automotive sensor supply regulation. It tracks an external reference voltage (e.g., 5 V MCU port) with ±0.5% accuracy, delivers up to 50 mA output current, maintains operation across 4–40 V input range, and operates from –40 °C to +150 °C junction temperature - enabling robust use in engine control units and exhaust gas sensors.
For engineers reviewing the TLE4250GHTSA1 datasheet, TLE4250GHTSA1 pinout, TLE4250GHTSA1 application, or TLE4250GHTSA1 equivalent, key selection criteria include tracking accuracy under load variation, quiescent current in standby mode (<20 µA), reverse polarity protection, short-circuit immunity, and SCT-595 package thermal performance at high ambient temperatures.
Technical Context
The TLE4250GHTSA1 implements a precision voltage-tracking architecture using an internal error amplifier comparing output voltage against the ADJ pin reference. Its enable function is integrated into the ADJ input (high-active), eliminating need for separate control logic.
It features dual ground pins (pins 2 and 5) internally connected for low-impedance return path, supports output capacitor ESR between 2 Ω and 7 Ω, and includes thermal shutdown triggered at ~165 °C junction temperature with automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output tracking accuracy | ±5 mV (typ.) at VI = 6–16 V, IQ = 1–10 mA - ensures stable sensor biasing under nominal battery conditions |
| Max output current | 50 mA - sufficient to power multiple analog sensors or Hall-effect ICs without external boost |
| Drop voltage | 100–300 mV at IQ = 10 mA - enables operation down to ~4.7 V input when tracking 5 V reference |
| Quiescent current (standby) | 10–20 µA at VADJ = 0 V - preserves battery life in always-on vehicle modules |
| Input voltage range | 4–40 V - accommodates cold-crank (4.5 V), normal operation (13.5 V), and load-dump transients (up to 40 V) |
| Junction temperature range | –40 °C to +150 °C - qualified for under-hood placement near exhaust manifolds or turbochargers |
| Reverse polarity protection | Withstands –42 V applied - eliminates need for external series diode in battery-reversed fault scenarios |
Pinout & Package
Package: SCT-595 - ultra-compact surface-mount package (2.9 mm × 2.8 mm × 1.1 mm), thermally enhanced with exposed pad (pin 5), rated for 99 K/W junction-to-ambient (PCB-mounted, 300 mm² heatsink).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ADJ | Tracking reference & enable input | High-active digital enable; also accepts analog reference (2.0–36 V); pulls <0.5 µA; disables output when <0.8 V |
| 2 - GND | Power ground | Internally bonded to pin 5; provides low-inductance return for output current and thermal path |
| 3 - I | Main supply input | Accepts unregulated automotive rail (4–40 V); includes internal overvoltage clamp to 45 V |
| 4 - Q | Regulated output | Delivers tracked voltage; requires ≥1 µF ceramic capacitor with 2–7 Ω ESR for stability |
| 5 - GND | Thermal & power ground | Exposed thermal pad; must be soldered to PCB copper pour for thermal management and noise reduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated reverse polarity protection | Eliminates external series diode, reducing BOM count and forward drop loss in battery-connected systems |
| Adjust/Enable dual-function pin | Reduces system GPIO usage - same pin configures tracking reference and enables/disables regulator via MCU port |
| Short-circuit protected output | Current-limited foldback behavior prevents thermal runaway during sustained output shorts in harsh environments |
| Overtemperature shutdown with hysteresis | Auto-recovers after cooldown - avoids permanent latch-off during transient thermal overload (e.g., hot soak) |
| Low ESR capacitor compatibility | Stable with 2–7 Ω ESR output caps - supports cost-effective X5R/X7R ceramics instead of expensive low-ESR tantalums |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage tracking applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV71750PDBVR | Fixed 5 V LDO (not tracking); 150 mA max; no reverse polarity protection; max VI = 5.5 V | Suitable only for post-regulated 5 V domains, not direct battery connection | Select only if input is already regulated and reverse fault risk is mitigated externally |
| MAX1725EUT+T | Tracking LDO with ±1.5% accuracy; 100 mA output; no reverse polarity or thermal shutdown | Lacks automotive-grade protection; limited to industrial temp range (–40 °C to +85 °C) | Use where cost is critical and environmental stressors (load dump, reverse battery) are absent |
Compared with TLV71750PDBVR and MAX1725EUT+T, the TLE4250GHTSA1 uniquely combines ±0.5% tracking accuracy, reverse polarity survival, and 150 °C operation - making it the sole choice for direct-battery-connected automotive sensor supplies requiring functional safety compliance.

FAQ
What is the minimum input voltage required for stable regulation?
The TLE4250GHTSA1 requires a minimum input voltage of 4 V to maintain regulation. Below this threshold, output voltage drops proportionally with input due to insufficient headroom for the internal pass element. Stable tracking is guaranteed only when VI ≥ VADJ + Vdr (e.g., ≥5.1 V for 5 V reference at 10 mA load), per datasheet Section 6.
Can the ADJ pin be driven directly by a microcontroller GPIO?
Yes - the ADJ pin accepts TTL/CMOS-compatible logic levels and draws only 0.1–0.5 µA. A 5 V-tolerant MCU GPIO can directly enable/disable the device or source the reference voltage. For tracking, connect via a series resistor if the MCU port cannot sink/source >1 mA during transient events.
Is an external diode required for reverse polarity protection?
No - the TLE4250GHTSA1 integrates reverse polarity protection and withstands –42 V applied to the I pin without damage or latch-up. This eliminates the need for an external series diode, reducing power loss and board space in battery-connected designs.
What output capacitor specifications are mandatory for stability?
A minimum 1 µF ceramic capacitor with ESR between 2 Ω and 7 Ω is mandatory at the Q pin. Capacitors outside this ESR range risk oscillation or poor transient response. The datasheet provides stability boundaries in Figure 8 (AED02917/AED02918) for 1 µF and 2.2 µF values.
