Description and Introduction

Low-Voltage (1.24V) Adjustable Precision Shunt Regulators The LMV431IM5X is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage Range:** 1.24V to 6V (adjustable via external resistors).
- **Reference Voltage:** 1.24V (typical).
- **Operating Current Range:** 60µA to 15mA.
- **Line Regulation:** 0.2mV (typical) at 5V.
- **Load Regulation:** 0.4mV (typical).
- **Temperature Range:** -40°C to +125°C.
- **Package:** SOT-23-5.
- **Accuracy:** ±1% (typical at 25°C).
- **Low Output Noise:** Suitable for precision applications.

### **Descriptions:**
- The LMV431IM5X is a low-voltage variant of the TL431, optimized for battery-powered and low-voltage systems.
- It functions as a precision voltage reference and error amplifier in shunt regulator configurations.
- It is commonly used in power supplies, battery chargers, and voltage monitoring circuits.

### **Features:**
- **Low Operating Voltage:** Works down to 1.24V.
- **Low Quiescent Current:** 60µA (typical), improving efficiency.
- **Adjustable Output:** Customizable via external resistors.
- **Wide Temperature Range:** Suitable for industrial applications.
- **Stable with Capacitive Loads:** Ensures reliable performance.
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.

This device is ideal for applications requiring precision voltage regulation in low-power systems.
