Product details
Overview
TLE4295GV50HTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, delivering 5.0 V ±4% output at up to 30 mA with dropout voltage as low as 0.25 V at 20 mA. It features power-fail open-collector output, reverse-polarity protection, and thermal shutdown-designed for microcontroller supply in harsh automotive environments.
For engineers reviewing the TLE4295GV50HTSA1 datasheet, TLE4295GV50HTSA1 pinout, TLE4295GV50HTSA1 application, or TLE4295GV50HTSA1 equivalent, key selection criteria include its AEC-Q100 qualification, 45 V max input, -40°C to +150°C junction temperature range, and integrated short-circuit/overtemperature protection for under-hood electronics.
Technical Context
The device implements a band-gap reference-based control loop with saturation detection and thermal foldback, enabling stable regulation across wide input (VI = VQ,nom + 0.5 V to 45 V) and temperature (-40°C to +150°C) ranges. Its PF pin provides undervoltage indication via open-collector logic-level output tied to ground during fault conditions.
Protection architecture includes reverse-polarity tolerance, current-limited output (30 mA typ.), and automatic thermal shutdown that disables the pass transistor above Tj = +150°C. Output capacitor requirement is specified as CQ ≥ 2.2 µF with ESR ≤ 5 Ω (tantalum recommended).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.00 V ±4% (4.80–5.20 V), regulated over 1 mA–30 mA load and input 6 V–40 V |
| Dropout Voltage | 0.25 V (typ.) at 20 mA load-enables operation with minimal headroom, e.g., 5.25 V input for 5.0 V output |
| Max Input Voltage | 45 V absolute maximum; functional range starts at VQ,nom + 0.5 V = 5.5 V |
| Quiescent Current | 2 µA–4 mA (load-dependent); 120–200 µA at light load (<1 mA)-critical for always-on automotive modules |
| Power Fail Output | Open-collector PF pin pulled low during undervoltage, overload, or output saturation-directly interfaces with MCU reset or monitoring GPIO |
| Thermal Protection | Automatic shutdown at Tj ≥ +150°C; restarts after cooldown-prevents permanent damage during sustained overload |
| Short-Circuit Protection | Current-limited to ≤30 mA under output short-maintains safe power dissipation without external fusing |
Pinout & Package
Delivered in PG-SCT595-5: a 5-pin, leadless, surface-mount package (2.9 mm × 1.6 mm × 0.6 mm) with exposed thermal pad, optimized for high-density automotive PCB layouts and thermal performance (RthJSP = 30 K/W to pin 5).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PF) | Power fail indicator | Open-collector output; sinks current when VI drops below threshold or output saturates-requires external pull-up for logic-level signaling |
| 2 (GND) | Ground reference | Primary ground connection; electrically tied to pin 5 internally-must be low-impedance path to system ground plane |
| 3 (I) | Input voltage supply | Accepts 5.5 V–45 V DC; requires local ceramic bypass (≥100 nF) near pin for stability and transient immunity |
| 4 (Q) | Regulated output | 5.0 V source; requires ≥2.2 µF tantalum capacitor (ESR ≤5 Ω) to GND for loop stability and ripple suppression |
| 5 (GND) | Ground reference | Secondary ground terminal; bonded to pin 2 internally-provides additional thermal conduction path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Qualified per Grade 0 (-40°C to +150°C) for engine control, body electronics, and ADAS sensors |
| Reverse polarity protection | Withstands -42 V input without damage-eliminates need for external series diode in battery-reversed scenarios |
| Integrated thermal shutdown | Turns off pass element at Tj ≥ +150°C and auto-recovers-avoids thermal runaway in sealed enclosures |
| Low quiescent current at light load | 120–200 µA at IQ < 1 mA-extends battery life in sleep-mode vehicle networks (e.g., CAN wake-up receivers) |
| Stable with low-ESR capacitors | Validated with 2.2 µF tantalum (ESR ≤5 Ω); avoids instability issues common with ceramic-only solutions |
Applications
| Engine Control Unit (ECU) Power Supply | Body Control Module (BCM) Sensor Bias |
|---|---|
Use Scenario: Supplies 5.0 V to MCU core and peripheral I/O in gasoline/diesel engine management systems exposed to load dump transients and under-hood temperatures. IC Role / Device Role / Timing Role: Primary post-regulator for 12 V battery-derived rail; provides clean, protected 5.0 V for safety-critical logic and ADC references. Use Value: Dropout voltage ≤0.25 V ensures regulation during cranking (battery dips to ~6 V), while thermal shutdown prevents failure during prolonged idle heat soak. | Use Scenario: Powers door lock actuators, ambient light sensors, and LIN transceivers in vehicle body electronics with intermittent 12 V supply. IC Role / Device Role / Timing Role: Local LDO for isolated sensor sub-systems; PF pin signals undervoltage to BCM microcontroller before brownout.

Use Scenario: Provides regulated 5.0 V to image sensor interface, ISP, and serial communication ICs in front/rear-view cameras mounted near headlights or grilles. IC Role / Device Role / Timing Role: Secondary regulator downstream of buck converter; decouples noise-sensitive imaging circuitry from switching supply ripple. Use Value: PSRR ≥60 dB at 100 Hz suppresses low-frequency ripple from upstream converters; -40°C to +150°C rating matches camera housing thermal profile. | Use Scenario: Supplies 5.0 V to position encoder interface, CAN controller, and watchdog timer in EPS motor control units located near steering column. IC Role / Device Role / Timing Role: Safety-relevant power domain supervisor; PF output triggers system fail-safe state on input sag or internal fault. Use Value: AEC-Q100 Grade 0 qualification ensures reliability under mechanical vibration and thermal cycling; short-circuit limiting protects against encoder wiring faults. |
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 5.0 V output, 1 A max, TO-220/SOT-223 package, no PF output or AEC-Q100 qualification | Designed for industrial/commercial use; lacks automotive fault signaling and extended temperature support | Select only for non-automotive prototypes or cost-sensitive non-safety designs where PF and Grade 0 are not required |
| TLV73350PDBVR | 5.0 V output, 300 mA, SOT-23-5 package, 170 mV dropout, no PF pin or reverse-polarity protection | Targeted at portable electronics; lacks automotive-grade thermal/ESD robustness and fault reporting | Use where higher output current and smaller footprint are prioritized over automotive protection features |
Compared with NCP1117ST50T3G and TLV73350PDBVR, TLE4295GV50HTSA1 uniquely combines AEC-Q100 Grade 0 qualification, integrated PF signaling, reverse-polarity tolerance, and thermal shutdown-making it the only choice for production automotive subsystems requiring functional safety-aware power supervision.

FAQ
What is the minimum input voltage required for regulation at 5.0 V output?
The functional input range begins at VQ,nom + 0.5 V = 5.5 V. Below this, regulation is not guaranteed-the device may enter dropout or disable output depending on load and temperature. For reliable 5.0 V output, maintain input ≥5.5 V across all operating conditions including cold cranking.
Can the PF pin drive an LED directly without a current-limiting resistor?
No. The PF pin is an open-collector NPN output rated for ≤500 µA sink current. Driving an LED requires an external current-limiting resistor to prevent exceeding this limit and damaging the internal transistor. Typical configuration uses 10 kΩ pull-up to 5 V and 1 kΩ series resistor to LED anode.
Is a ceramic output capacitor acceptable instead of tantalum?
The datasheet specifies ≥2.2 µF with ESR ≤5 Ω and explicitly recommends tantalum. Ceramic capacitors typically have ESR < 100 mΩ, which can cause instability or oscillation. If ceramic must be used, add a 4.7 Ω–5 Ω damping resistor in series with the capacitor to meet ESR requirements.
Does TLE4295GV50HTSA1 support adjustable output voltage via external resistors?
No. It is a fixed-output regulator with internal feedback network set to 5.0 V. There is no adjust pin or external resistor option. For adjustable output, consider Infineon's TLE4275 or TLE7273 families, which provide external feedback capability and higher current ratings.
