Infineon Technologies IFX20002MBV33HTSA1

Overview

IFX20002MBV33HTSA1 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 ≤300 mV across -40°C to +125°C. It features inhibit control, reverse polarity protection, short-circuit and overtemperature shutdown, and stable operation with ≥3.3 µF ceramic output capacitor. Designed for industrial microcontroller and sensor supply under harsh conditions.

For engineers reviewing the IFX20002MBV33HTSA1 datasheet, IFX20002MBV33HTSA1 pinout, IFX20002MBV33HTSA1 application, or IFX20002MBV33HTSA1 equivalent, key selection criteria include its 45 V max input, <5 µA standby current via INH, thermal protection behavior, and compatibility with small-footprint PCB layouts requiring robust fault resilience.

Technical Context

The IFX20002MBV33HTSA1 integrates bandgap reference, saturation control, and thermal shutdown circuitry into a single die. Its inhibit logic enables active-high enable (VINH ≥2.2 V) and active-low disable (VINH ≤0.4 V), reducing quiescent current to ≤5 µA in stand-by mode.

It operates across 4.0–45 V input range while maintaining regulated 3.3 V output with load regulation of ≤40 mV (1–25 mA) and line regulation of ≤25 mV (VQ,nom+0.5 V to 36 V). Protection functions-including reverse polarity, short-circuit current limiting (30 mA trip), and junction temperature cutoff at ~150°C-are embedded and non-latching.

FAQ

What is the minimum input voltage required for regulation at 3.3 V output?

The IFX20002MBV33HTSA1 requires a minimum input voltage of 4.0 V to maintain regulation at 3.3 V output, as specified in its functional range. Below this, dropout behavior begins-output voltage drops linearly with input. At 20 mA load, dropout is ≤300 mV, meaning regulation holds down to ~3.6 V input.

Can this regulator operate without an output capacitor?

No. The device requires a minimum 3.3 µF ceramic output capacitor with ESR ≤2 Ω at 10 kHz for stability, as confirmed in the datasheet's application information and electrical characteristics. Omitting or undersizing this capacitor risks oscillation, poor transient response, and potential thermal stress during load steps.

Is the INH pin compatible with 3.3 V logic levels?

Yes. The INH pin accepts standard 3.3 V CMOS logic: turn-on threshold is guaranteed ≥2.2 V, and turn-off threshold is ≤0.4 V. With typical 3.3 V GPIO outputs (2.4–3.3 V high, 0–0.4 V low), it achieves reliable enable/disable control without level-shifting circuitry.

Does this part support parallel operation for higher current?

No. The IFX20002MBV33HTSA1 is not designed for parallel operation. Its internal current-limiting and thermal protection are per-device; paralleling would cause unequal current sharing and premature shutdown. For >30 mA, select a higher-current LDO or use a discrete pass transistor solution with external current sensing.
