Infineon Technologies TLE4296GV30NTSA1

Overview

TLE4296GV30NTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, delivering 3.0 V ±4% output at up to 30 mA with 0.25 V typical dropout at 20 mA. It features inhibit-controlled standby mode (<1 µA quiescent current), reverse-polarity protection, short-circuit and overtemperature shutdown, and operates from 4.0 V to 45 V input across –40 °C to 150 °C junction temperature - deployed in automotive microcontroller power rails.

For engineers reviewing the TLE4296GV30NTSA1 datasheet, TLE4296GV30NTSA1 pinout, TLE4296GV30NTSA1 application, or TLE4296GV30NTSA1 equivalent, key selection criteria include dropout voltage under load, inhibit logic thresholds, thermal resistance (R_thj-pin = 30 K/W), ESR-compatible output capacitor requirements (3–10 Ω), and AEC-Q100 qualification for under-hood use.

Technical Context

The TLE4296GV30NTSA1 integrates bandgap reference, saturation control, and thermal shutdown circuitry in a single die. Its inhibit input (Pin 1) enables high-level activation (V_INH,high ≥ 2.2 V) and low-level disable (V_INH,low ≤ 0.4 V), reducing quiescent current to ≤1 µA in standby.

Regulation is maintained across 4.0–45 V input range with line regulation ≤20 mV and load regulation ≤20 mV. Output stability requires a 2.2 µF ceramic capacitor with ESR between 3 Ω and 10 Ω, and PSRR reaches 60 dB at 100 Hz.

Key Specifications

Pinout & Package

PG-SCT595-5 is a 5-pin, leadless surface-mount package (2.9 mm × 2.5 mm × 0.75 mm) with exposed thermal pad (pin 5). Pin 2 and pin 5 are internally connected GND terminals for enhanced thermal conduction and low-inductance grounding.

FAQ

What is the minimum input voltage required for regulation at full 30 mA load?

The TLE4296GV30NTSA1 requires VIN ≥ 3.25 V to maintain 3.0 V output at 30 mA, based on its 0.25 V typical dropout voltage. However, functional operation starts at 4.0 V per datasheet operating range - below this, regulation is not guaranteed even at light loads.

Can the output capacitor be smaller than 2.2 µF if using a low-ESR tantalum part?

No. The 2.2 µF minimum capacitance is mandatory for stability regardless of dielectric type. Using <2.2 µF violates the design condition for phase margin and may cause oscillation, even with low-ESR tantalum. ESR must remain within 3–10 Ω - tantalum typically falls outside this range.

Is the inhibit input compatible with 3.3 V logic without level shifting?

Yes. With V_INH,high ≥ 2.2 V and V_INH,low ≤ 0.4 V, the inhibit pin accepts standard 3.3 V CMOS logic levels directly. No level shifter is needed when driven by 3.3 V microcontrollers or FPGAs.

Does the device support parallel operation for higher output current?

No. The TLE4296GV30NTSA1 is not designed for parallel operation. Its output stage lacks current-sharing circuitry, and mismatched dropout voltages would cause one unit to dominate load current - risking thermal imbalance and premature failure.
