Product details
Overview
TLE4296GV33NTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, designed for automotive microprocessor supply under harsh conditions. It delivers 3.3 V ±4% output at up to 30 mA load, with 0.25 V typical dropout at 20 mA, -40 °C to 150 °C junction temperature range, and inhibit-controlled standby mode consuming ≤1 µA.
For engineers reviewing the TLE4296GV33NTSA1 datasheet, TLE4296GV33NTSA1 pinout, TLE4296GV33NTSA1 application, or TLE4296GV33NTSA1 equivalent, key selection factors include its AEC-Q100 qualification, reverse-polarity protection, short-circuit and overtemperature shutdown, and 45 V maximum input voltage capability for 12 V/24 V automotive systems.
Technical Context
The TLE4296GV33NTSA1 integrates bandgap reference, saturation control, thermal shutdown, and inhibit logic in a single die. Its architecture enables stable regulation across 4.3–45 V input while maintaining ≤4% output accuracy over full temperature and load range (1–30 mA).
It uses internal current limiting and foldback to enforce 30 mA output cap, with dedicated INH pin (VIH ≥ 2.2 V, VIL ≤ 0.4 V) enabling system-level power sequencing. Ground pins (2 and 5) are internally bonded for low-inductance return path, critical for EMI-sensitive automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.30 V ±4% (3.17–3.43 V), specified at 1–30 mA load and -40 °C to 150 °C |
| Dropout Voltage | 0.25 V typ. at 20 mA - enables regulation down to 3.55 V input in worst-case temp/load |
| Max Input Voltage | 45 V - supports 24 V commercial/industrial rails and transient spikes per ISO 7637-2 |
| Quiescent Current | ≤1 µA in inhibit-off standby - extends battery life in always-on vehicle modules |
| Output Current Limit | 30 mA - sufficient for MCU core/logic supply, not for high-current peripherals |
| Thermal Shutdown | Active at Tj ≥ 150 °C - protects against sustained overload or poor heatsinking |
| ESR Range for CQ | 3–10 Ω at 100 kHz - mandates use of ceramic or low-ESR tantalum capacitor ≥2.2 µF |
Pinout & Package
Package: PG-SCT595-5 - 5-pin thermally enhanced SMD package with exposed pad (pin 5 = GND), footprint compatible with JEDEC MO-229 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INH) | Inhibit control input | High-active logic: ≥2.2 V enables regulation; ≤0.4 V forces shutdown and <1 µA IQ |
| 2 (GND) | Power ground reference | Internally connected to pin 5; must be low-impedance PCB plane for stability and thermal conduction |
| 3 (IN) | Unregulated input supply | Accepts 4.3–45 V DC; requires local 100 nF ceramic decoupling near pin |
| 4 (Q) | Regulated 3.3 V output | Requires ≥2.2 µF output capacitor with 3–10 Ω ESR for loop stability and transient response |
| 5 (GND) | Thermal ground / power return | Exposed pad; primary thermal path to PCB copper; must be soldered to ≥1 cm² GND pour |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 0 (-40 °C to +150 °C), validated for automotive ECU power rails per stress test requirements |
| Reverse polarity protection | Withstands -42 V input without damage - eliminates need for external series diode in battery-reversal-prone systems |
| Short-circuit protected output | Current-limited to ≤30 mA during fault; auto-recovers when short removed |
| Low quiescent current in standby | ≤1 µA at Tj < 85 °C with INH = 0.4 V - meets ISO 16750-2 "parking mode" leakage limits |
| Wide input voltage range | Operates from 4.3 V (start-stop compatible) to 45 V (load-dump tolerant) without external components |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Sensor Interface |
|---|---|

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, 170 mV dropout, no AEC-Q100, max 5.5 V input | Not suitable for 12 V/24 V automotive; limited to low-voltage infotainment subsystems | Select only for non-automotive, space-constrained designs requiring higher current |
| TPS7B6733QPWPRQ1 | 3.3 V, 200 mA, 300 mV dropout, AEC-Q100 Grade 1 (-40 °C to +125 °C), 40 V max input | Higher current but narrower temp range; lacks reverse-polarity protection | Prefer where >30 mA load needed and reverse-battery risk is mitigated externally |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, the TLE4296GV33NTSA1 uniquely combines AEC-Q100 Grade 0 rating, reverse-polarity immunity, and 45 V input tolerance - making it the only choice for under-hood modules exposed to load dump and battery reversal.

FAQ
What is the minimum input voltage required for regulation at full load?
The TLE4296GV33NTSA1 requires ≥4.3 V input to maintain 3.3 V output at 30 mA load across -40 °C to 150 °C, per Table 3. Below this, dropout occurs - e.g., at 20 mA load, 3.55 V input suffices due to 0.25 V typical dropout.
Can the INH pin be left floating in the application?
No. The INH pin must be actively driven: pulled high (>2.2 V) to enable regulation or low (<0.4 V) to enter standby. Floating may cause undefined state, erratic output, or excessive current draw due to internal bias uncertainty.
Is an external capacitor required on the Q pin, and what are its critical parameters?
Yes - a minimum 2.2 µF capacitor with ESR between 3 Ω and 10 Ω at 100 kHz is mandatory on the Q pin. Ceramic or low-ESR tantalum types meet this; aluminum electrolytics do not, risking instability and oscillation.
Does the device support parallel operation for higher current capability?
No. The TLE4296GV33NTSA1 is not designed for paralleling. Its internal current limit and thermal shutdown are per-unit; connecting outputs risks unequal current sharing, thermal runaway, and premature shutdown without performance gain.
