Product details
Overview
TLE4295GV33NTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, delivering 3.3 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) signaling, reverse polarity protection, short-circuit and overtemperature shutdown, and operates across -40°C to +150°C junction temperature for automotive microcontroller supply rails.
For engineers reviewing the TLE4295GV33NTSA1 datasheet, TLE4295GV33NTSA1 pinout, TLE4295GV33NTSA1 application, or TLE4295GV33NTSA1 equivalent, key selection criteria include guaranteed 3.3 V regulation under 45 V input, integrated fault signaling via PF pin, thermal shutdown behavior, quiescent current below 4 mA at full load, and AEC-Q100 qualification for under-hood use.
Technical Context
The device implements a bandgap reference-based control loop with saturation detection and thermal foldback, enabling stable regulation down to input voltages only 0.25 V above nominal output. Its internal protection logic disables the pass transistor during overtemperature or output short-circuit events, with automatic recovery upon fault clearance.
Power fail (PF) output asserts low during undervoltage, overload, or pass transistor saturation-providing system-level monitoring without external circuitry. The dual GND pins (pins 2 and 5) reduce thermal resistance to solder point (RthJSP = 30 K/W) and improve noise immunity in high-EMI automotive environments.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PF) | Open-collector power fail output | Drives low during undervoltage, overload, or saturation-requires external pull-up for system monitoring |
| 2 (GND) | Ground reference | Primary ground connection; electrically tied to pin 5 for low-inductance return path |
| 3 (I) | Input voltage supply | Accepts 4.3–45 V DC; must be decoupled externally near pin |
| 4 (Q) | Regulated output | 3.3 V output requiring ≥2.2 µF tantalum capacitor (ESR ≤5 Ω) to GND for stability |
| 5 (GND) | Secondary ground terminal | Thermally enhanced ground tie to exposed pad; reduces RthJSP to 30 K/W |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q100 Qualified | Validated for automotive Grade 0 (−40°C to +150°C) operation with lifetime reliability testing per stress test conditions |
| Low Dropout Performance | 0.25 V dropout at 20 mA enables stable 3.3 V rail even during cold-crank (VI ≥ 3.55 V) |
| Reverse Polarity Protection | Withstands −42 V input without damage-eliminates need for external series diode in battery-reversal-prone systems |
| Thermal Shutdown Recovery | Auto-restart after cooling-prevents latch-up during transient overheating without manual reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout automotive regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PDBVR | 300 mA output, 250 mV dropout, no PF pin, not AEC-Q100 qualified | Consumer/industrial use only; lacks fault signaling and automotive qualification | Select only for non-automotive designs where higher current and smaller dropout are prioritized over safety monitoring |
| TPS7B6733QPWPRQ1 | 250 mA output, integrated enable, 300 mV dropout, AEC-Q100 Grade 1 (−40°C to +125°C) | Limited high-temp capability vs. TLE4295GV33NTSA1's Grade 0 rating | Prefer when system-level enable control is required and junction temperature stays below 125°C |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, TLE4295GV33NTSA1 uniquely combines AEC-Q100 Grade 0 qualification, integrated PF signaling, reverse polarity tolerance, and 150°C operation-making it the only choice for under-hood applications demanding full fault visibility and extreme thermal resilience.

FAQ
What is the minimum input voltage required for regulation at full 30 mA load?
The minimum input voltage is 3.55 V-calculated as nominal output (3.3 V) plus typical dropout (0.25 V). At this input, the device maintains regulation within ±4% across −40°C to +150°C junction temperature, verified per datasheet Section 4.1.4.
How does the power fail (PF) pin behave during thermal shutdown?
During thermal shutdown, the PF pin asserts low-identical to its behavior during undervoltage or overload. This unified fault signaling allows single-wire monitoring of all critical failure modes without additional logic, as confirmed in datasheet Section 2.2 and Figure 1 block diagram.
Is an external capacitor required on the Q pin, and what are its specifications?
Yes: a minimum 2.2 µF tantalum capacitor with ESR ≤5 Ω at 10 kHz is mandatory between Q and GND for stability, per datasheet Section 4.1.9. Ceramic capacitors are not recommended due to insufficient ESR, which may cause oscillation under transient load conditions.
Does TLE4295GV33NTSA1 support reverse battery connection, and what is the limit?
Yes: it withstands −42 V applied to the I pin with respect to GND without damage, as specified in Table 2 (Absolute Maximum Ratings, P_3.1.1). This reverse polarity protection eliminates the need for external series diodes in automotive battery interfaces.
