Product details
Overview
IFX20001MBV33HTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering a fixed 3.3 V output at up to 30 mA, with ≤300 mV dropout across -40°C to +125°C, integrated inhibit control, short-circuit and reverse-polarity protection, and housed in a thermally enhanced PG-SCT595-5 package. It serves as a robust standby or microcontroller/sensor supply in harsh industrial environments.
For engineers reviewing the IFX20001MBV33HTSA1 datasheet, IFX20001MBV33HTSA1 pinout, IFX20001MBV33HTSA1 application, or IFX20001MBV33HTSA1 equivalent, key selection criteria include dropout voltage under load, quiescent current in inhibit mode (<5 µA), ±4% output accuracy over temperature and line, thermal resistance (RthJA = 81 K/W on 2s2p board), and PG-SCT595-5 package compatibility with high-density PCB layouts.
Technical Context
The IFX20001MBV33HTSA1 implements a bandgap-referenced control loop with saturation control and integrated thermal shutdown circuitry that disables regulation when junction temperature exceeds safe limits. Its inhibit input enables external logic-level control of output state, supporting energy-sensitive system sleep modes.
It operates across an input range of 4.0–45 V while maintaining 3.3 V ±4% output accuracy, supports ceramic output capacitors ≥3.3 µF with ESR 2.5–6 Ω, and features built-in protections against short circuit, reverse polarity, and overtemperature-each designed for fault recovery rather than continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (3.17–3.43 V) at 1–30 mA load; ensures stable MCU core/sensor bias under varying line and temperature. |
| Dropout Voltage | ≤300 mV at 20 mA; enables regulation from 3.6 V input, critical for battery-backed or low-headroom systems. |
| Quiescent Current | ≤5 µA in inhibit mode; reduces standby power in always-on industrial nodes without compromising wake-up latency. |
| Input Voltage Range | 4.0–45 V; accommodates wide industrial rails including 12/24/36 V systems with transient margin. |
| Thermal Resistance | RthJA = 81 K/W (2s2p board); enables 30 mA operation at Tj ≤125°C with minimal copper area. |
| Protection Functions | Short-circuit, reverse-polarity, and overtemperature shutdown; prevents catastrophic failure during field faults. |
| Output Capacitor | ≥3.3 µF ceramic, ESR 2.5–6 Ω @10 kHz; ensures stability without electrolytic bulk capacitance. |
Pinout & Package
Package: PG-SCT595-5 - thermally enhanced 5-pin SMD package with exposed thermal pad, footprint optimized for high-power density and efficient PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INH) | Inhibit input | Active-high logic control: ≥2.2 V enables output; ≤0.4 V disables output and reduces IQ to ≤5 µA. |
| 2 (GND) | Ground reference | Primary ground connection tied internally to pin 5; must be low-impedance path to minimize noise and thermal rise. |
| 3 (I) | Input voltage | Accepts 4.0–45 V DC; requires local ceramic decoupling (≥100 nF) near pin for transient immunity. |
| 4 (Q) | Regulated output | 3.3 V source; requires ≥3.3 µF ceramic capacitor with 2.5–6 Ω ESR for loop stability and ripple suppression. |
| 5 (GND) | Ground reference | Secondary ground tied to pin 2; connects to exposed thermal pad for optimal heat transfer to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Low-dropout operation | 250–300 mV dropout at 20 mA enables use with input voltages as low as 3.6 V while sustaining 3.3 V output. |
| Inhibit-controlled standby | Reduces total current draw to ≤5 µA when INH < 0.4 V, enabling ultra-low-power sleep states in automation controllers. |
| Integrated fault protection | Auto-shutdown on short circuit, reverse polarity, or Tj >125°C; recovers automatically after fault removal and cooldown. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLD5098EL | Fixed 3.3 V output, 150 mA rating, higher quiescent current (25 µA typ), no inhibit function. | Suitable for higher-current loads but lacks enable control; requires external transistor for standby gating. | Select if load exceeds 30 mA and inhibit is not required; verify thermal design for 150 mA continuous operation. |
| MCP1703T-3302E/MB | 3.3 V output, 250 mA, 2 µA quiescent current, no reverse-polarity protection, SOIC-8 package. | Larger footprint and lower thermal performance (RthJA ≈ 150 K/W); lacks integrated reverse-voltage blocking. | Prefer for ultra-low-IQ designs where board space and thermal constraints permit SOIC-8; add external diode for reverse protection. |
Compared with TLD5098EL and MCP1703T-3302E/MB, IFX20001MBV33HTSA1 uniquely balances 30 mA capability, sub-5 µA inhibit current, reverse-polarity protection, and compact PG-SCT595-5 thermal packaging-making it optimal for space-constrained, fault-resilient industrial edge nodes.

FAQ
What is the minimum input voltage required for regulation at full 30 mA load?
The IFX20001MBV33HTSA1 requires a minimum input voltage of 3.6 V to maintain 3.3 V output at 30 mA, based on its maximum 300 mV dropout specification. At 20 mA, typical dropout is 250 mV, allowing regulation from 3.55 V. Input below 4.0 V is outside the functional range per datasheet Table 3 and may result in undefined behavior or reduced protection margin.
Can the output capacitor be smaller than 3.3 µF if using a low-ESR tantalum instead of ceramic?
No. The datasheet explicitly specifies ≥3.3 µF ceramic capacitors with ESR between 2.5 Ω and 6 Ω at 10 kHz for IFX20001MBV33HTSA1. Tantalum capacitors typically exhibit higher ESR drift with temperature and aging, risking instability or oscillation. Deviating from the recommended capacitor type and ESR range voids guaranteed stability and may cause output ripple or thermal shutdown.
Does the inhibit function support partial disable (e.g., reduce output current) or only full on/off control?
The inhibit function provides only binary on/off control: high logic level (≥2.2 V) enables full 30 mA regulation; low logic level (≤0.4 V) disables the output entirely and reduces quiescent current to ≤5 µA. There is no intermediate or current-throttling mode-the device is either fully active or fully inhibited.
Is this part qualified for use in automotive applications such as body control modules?
No. The IFX20001MBV33HTSA1 is explicitly stated in the datasheet as "not qualified and manufactured according to the requirements of Infineon Technologies with regards to automotive and/or transportation applications." For automotive use, Infineon recommends its TLx series (e.g., TLE4274, TLS850B), which meet AEC-Q100 Grade 1 or 0 requirements and include extended temperature and reliability validation.
