IFX20001MBV33HTSA1: Technical Datasheet and Application Overview

The IFX20001MBV33HTSA1 is a high-performance, low-dropout (LDO) voltage regulator from Infineon Technologies, designed to deliver a fixed 3.3V output from a higher input voltage source. This component is engineered for applications requiring a stable, clean, and reliable power supply under challenging conditions. Its compact, surface-mount package makes it ideal for space-constrained PCB designs across automotive, industrial, and consumer electronics.

A core feature of this LDO is its very low dropout voltage, which enables it to continue regulating the output voltage even when the input voltage dips very close to the output level. This is critical for battery-powered applications where maintaining voltage stability is essential as the battery discharges. Furthermore, the device boasts an impressely low quiescent current, enhancing energy efficiency and prolonging battery life in always-on systems.

The regulator incorporates advanced protection mechanisms to ensure system safety and longevity. Key among these are internal current limiting and thermal shutdown circuits. These features protect the IC from damage due to overload conditions, short circuits, and excessive junction temperature. The device also demonstrates excellent line and load regulation, maintaining a stable output despite fluctuations in the input voltage or variations in the current drawn by the load.

Typical applications for the IFX20001MBV33HTSA1 are extensive. It is a perfect fit for powering microcontrollers (MCUs), sensors, and other digital logic circuits that demand a noise-free power rail. Its robust design and qualification make it particularly suitable for the harsh environment of automotive electronics, such as infotainment systems, dashboard clusters, and body control modules. It is also widely used in industrial control systems, smart meters, and portable handheld devices.
