Introduction

The LM4121AIM5X-1.2 is a high-accuracy multi-voltage reference product from third-party manufacturers, designed specifically for portable device applications. The voltage reference is designed to provide excellent performance and features over a wide operating temperature range. The LM4121AIM5X-1.2 is a voltage regulator and in-line power conversion device intended for direct supply of a wide range of battery and system voltages. It is capable of handling the widest range of operating conditions (from 0.6V to 6V) and providing the best GFSK and long-term stability over its entire operating range.

Application Field

The LM4121AIM5X-1.2 is ideal for use in applications such as Portable Electronics and Automobile Electronics where the power supply voltage often fluctuates and needs to be kept to a constant level. The device can handle the widest range of input voltages, eliminating the need for a separate voltage regulator to be used in conjunction with the system.The reference display products can also be used in various low power system applications such as Medical Electronics and Telecommunication Equipment. The device is designed to provide the best GFSK and long-term stability over its entire operating range in such applications.

Features

The LM4121AIM5X-1.2 has several features. First, it has low differential output impedance, which ensures low output noise and stable line regulation. Second, it has high accuracy voltage rating over temperature, which ensures that the device maintains its accuracy even when used in extreme temperatures. Third, it has built-in reverse polarity protection to avoid damage from reverse input cables. Finally it has an active loop control output that can be used to monitor the device’s output voltage.

Working Principle

The LM4121AIM5X-1.2 works by taking an input voltage and converting it to a regulated output voltage. The device has an internal circuitry to ensure that the output voltage is always a predetermined set voltage, even when the input voltage changes. This is done via the use of a variable resistor, a zener diode and an operational amplifier. The variable resistor adjusts the output voltage, while the zener diode ensures that the output voltage cannot exceed the predetermined limit (the zener breakdown voltage). The operational amplifier then amplifies the difference between the output voltage and the zener breakdown voltage, providing the final output voltage regulation.
