IFX20002MBV33HTSA1: Technical Specifications and Application Overview

The IFX20002MBV33HTSA1 is a highly integrated, low-dropout (LDO) voltage regulator from Infineon Technologies, designed to deliver exceptional performance and reliability for a wide range of modern electronic applications. This component is engineered to provide a stable and clean 3.3V output voltage from a higher input source, making it a fundamental building block in power management systems.

Technical Specifications

This voltage regulator is characterized by its key electrical parameters. It supports a wide input voltage range from 2.5V to 5.5V, accommodating common power sources like single-cell Li-ion batteries (3.7V) or standard 5V rails. Its primary function is to regulate this input down to a precise 3.3V output with a maximum output current of 200 mA, sufficient for powering microcontrollers, sensors, and communication modules.

A critical feature of this LDO is its extremely low dropout voltage. Even when the input voltage dips very close to the output level, the device continues to regulate effectively, maximizing battery life and operational stability in portable devices. Furthermore, it boasts a very low quiescent current in the microampere range, which is paramount for applications where power conservation is critical, significantly reducing the overall system's power consumption during active and standby modes.

The device incorporates essential protection mechanisms, including over-current protection (OCP) and thermal shutdown, safeguarding both the regulator itself and the downstream components from damage under fault conditions. Housed in a compact SOT23-5 package, the IFX20002MBV33HTSA1 offers an excellent performance-to-size ratio, making it ideal for space-constrained PCB designs.

Application Overview

The combination of its small form factor, high efficiency, and robust performance makes the IFX20002MBV33HTSA1 exceptionally versatile. Its primary applications include:

Portable and Battery-Powered Devices: Such as wearables, health monitors, and handheld terminals, where its low dropout and low quiescent current are vital for extending battery runtime.

Internet of Things (IoT) Nodes and Sensors: Used to provide a clean and stable voltage rail to the system-on-chip (SoC) and wireless connectivity modules (Wi-Fi, Bluetooth, LoRa).

Consumer Electronics: Including smartphones, tablets, and digital cameras, where it is used as a secondary regulator for specific sub-systems requiring noise-sensitive 3.3V power.

Industrial and Automotive Electronics: Providing reliable power for low-power controllers, sensors, and logic circuits in harsh environments, thanks to its built-in protections.

ICGOODFIND: The IFX20002MBV33HTSA1 stands out as a superior choice for designers seeking a reliable, efficient, and compact LDO solution. Its optimal balance of low dropout voltage, minimal quiescent current, and integrated protections makes it an indispensable component for power-sensitive and space-aware applications across consumer, industrial, and automotive markets.
