Product details
Overview
TLE4295GV26HTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, designed for automotive microcontroller supply under harsh conditions. It delivers 3.0 V output at ±4% tolerance, supports 30 mA load current, features power-fail open-collector output, and operates from -40°C to +150°C junction temperature with input up to 45 V.
For engineers reviewing the TLE4295GV26HTSA1 datasheet, TLE4295GV26HTSA1 pinout, TLE4295GV26HTSA1 application, or TLE4295GV26HTSA1 equivalent, key selection criteria include dropout voltage ≤0.4 V at 20 mA, thermal shutdown, reverse-polarity protection, and AEC-Q100 qualification for automotive use.
Technical Context
The TLE4295GV26HTSA1 integrates bandgap reference, control amplifier, and protection circuitry-including thermal shutdown, short-circuit limiting, and reverse-polarity immunity-within a single silicon die. Its PF (power fail) output asserts low during undervoltage, output saturation, or overload, enabling system-level fault detection.
It employs a PNP pass transistor architecture enabling ultra-low dropout (0.25 V typ. at 20 mA), stable regulation across 4 V to 45 V input range, and guaranteed operation over full automotive temperature range without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±4% - maintains MCU core logic supply within safe operating margin under load and temperature variation |
| Max Output Current | 30 mA - sufficient for low-power microcontrollers, CAN transceivers, or sensor interfaces |
| Dropout Voltage | 0.25 V (typ.) at 20 mA - enables regulation down to VI = VQ + 0.25 V, critical for cold-cranking scenarios |
| Quiescent Current | 2 µA (typ.) at light load - minimizes standby power loss in always-on vehicle modules |
| Operating Input Range | 4.5 V to 45 V - accommodates 12 V and 24 V automotive battery systems including load dump transients |
| Junction Temp Range | -40°C to +150°C - validated for under-hood placement per AEC-Q100 Grade 0 |
| Power Fail Output | Open-collector, active-low - provides direct interface to MCU interrupt or reset pin for brown-out detection |
Pinout & Package
Package: PG-SCT595-5 - 5-pin surface-mount package with exposed thermal pad, footprint-optimized for high thermal reliability in compact automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PF) | Power fail indicator | Open-collector output pulled low during undervoltage, overload, or output saturation - requires external pull-up for MCU interrupt signaling |
| 2 (GND) | Ground reference | Main ground connection tied internally to pin 5; must be low-inductance path to minimize noise coupling into regulation loop |
| 3 (I) | Input voltage supply | Accepts 4.5–45 V DC; requires local ceramic bypass capacitor (≥100 nF) near pin for transient immunity |
| 4 (Q) | Regulated output | 3.0 V output; requires ≥2.2 µF tantalum capacitor with ESR ≤5 Ω to ensure stability and transient response |
| 5 (GND) | Ground reference | Second ground terminal tied internally to pin 2; improves thermal dissipation and reduces ground bounce in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Reverse polarity protection | Withstands -42 V input without damage - eliminates need for external series diode in battery-reversal-prone installations |
| Thermal shutdown | Automatic turn-off above +150°C junction temperature with hysteresis - prevents permanent failure during sustained overload |
| Short-circuit protection | Current-limited to ≤30 mA during output short - maintains safe power dissipation without latch-up |
| AEC-Q100 qualified | Grade 0 (−40°C to +150°C) qualification - meets automotive reliability and stress-test requirements for safety-critical ECUs |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Sensor Interface |
|---|---|
Use Scenario: Powering 3.3 V or 5 V-compatible microcontrollers and LIN transceivers in door modules, lighting controllers, or seat control units. IC Role / Device Role / Timing Role: Primary 3.0 V LDO supplying MCU I/O and peripheral logic rails with fault reporting via PF pin. Use Value: Enables single-supply design from 12 V battery while providing brown-out detection and thermal resilience in confined enclosures. | Use Scenario: Regulating supply for pressure, temperature, or position sensors interfacing with engine ECU analog front-ends. IC Role / Device Role / Timing Role: Clean, stable 3.0 V bias source for precision ADC references and op-amp signal conditioning stages. Use Value: Maintains <±4% output accuracy across wide temperature and input voltage swings, ensuring sensor measurement integrity. |
| Advanced Driver Assistance Systems (ADAS) Camera Module | Electric Power Steering (EPS) Motor Controller |
Use Scenario: Supplying image signal processor (ISP) and MIPI interface logic in rear-view or surround-view camera ECUs. IC Role / Device Role / Timing Role: Secondary regulated rail decoupled from main 5 V domain, with PF output feeding ISP watchdog timer. Use Value: Low quiescent current (<2 µA) extends sleep-mode battery life; dropout performance sustains operation during cranking dips. | Use Scenario: Powering gate driver logic and current-sense amplifiers in EPS motor control boards mounted near steering column. IC Role / Device Role / Timing Role: Isolated 3.0 V supply for isolated gate drivers and isolated ADCs, leveraging dual-GND pins for noise separation. Use Value: Dual GND pins reduce ground loop interference; thermal shutdown prevents latch-up during motor stall events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PDBVR | 300 mA output, 1.2 V to 5.5 V adjustable, no PF output, max input 5.5 V | Not AEC-Q100 qualified; limited to infotainment or body electronics with stable 3.3 V input | Select only for non-automotive, low-current, non-safety-critical designs requiring higher output current |
| MAX1725EUT30+T | 30 mA output, 3.0 V fixed, no PF output, max input 28 V, -40°C to +85°C | Lacks automotive temp range and power-fail signaling; no reverse-polarity protection | Use where cost sensitivity outweighs functional safety requirements and thermal robustness |
Compared with TLV73330PDBVR and MAX1725EUT30+T, the TLE4295GV26HTSA1 uniquely combines AEC-Q100 Grade 0 qualification, integrated PF signaling, reverse-polarity immunity, and 45 V input capability - making it the only choice for under-hood, safety-relevant 3.0 V regulation.

FAQ
What is the minimum input voltage required for regulation at 3.0 V output?
The TLE4295GV26HTSA1 requires a minimum input voltage of VQ,nom + 0.5 V = 3.5 V to maintain regulation, per functional range specification. Below this threshold, the PF output goes low and regulation ceases. This ensures reliable startup after battery recovery from deep discharge or cranking dips.
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 pull-up resistor and series current-limiting resistor to avoid exceeding absolute maximum ratings and ensure predictable low-state voltage (<0.4 V).
Is the TLE4295GV26HTSA1 compatible with ceramic output capacitors?
No. The datasheet specifies a minimum 2.2 µF tantalum capacitor with ESR ≤5 Ω for stability. Ceramic capacitors have near-zero ESR and can cause oscillation due to phase margin degradation in this regulator's internal compensation network.
Does the device support parallel operation for higher current capability?
No. The TLE4295GV26HTSA1 lacks current-sharing features such as current-sense pins or master-slave synchronization. Parallel connection risks thermal imbalance and uncontrolled current hogging, violating absolute maximum ratings and voiding AEC-Q100 qualification.
