Description and Introduction

Precision Micropower Shunt Voltage Reference 3-SOT-23 -40 to 125 The TL4051C12QDBZT is a precision shunt voltage reference manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.225V (fixed)  
- **Initial Accuracy:** ±0.1% (A-grade)  
- **Temperature Coefficient (Tempco):** 20ppm/°C (typical)  
- **Operating Current Range:** 45µA to 15mA  
- **Low Output Noise:** 35µVrms (typical, 10Hz to 10kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- The TL4051 is a low-power, high-precision shunt voltage reference.  
- It provides a stable 1.225V output with excellent temperature stability.  
- Suitable for battery-powered and portable applications due to its low quiescent current.  

### **Features:**  
- **High Precision:** ±0.1% initial accuracy (A-grade)  
- **Low Power Consumption:** 45µA minimum operating current  
- **Wide Operating Current Range:** 45µA to 15mA  
- **Low Temperature Drift:** 20ppm/°C (typical)  
- **Small Form Factor:** SOT-23-3 package  
- **Low Noise Output:** 35µVrms (typical)  
- **Wide Operating Temperature Range:** -40°C to +125°C  

This device is commonly used in precision analog circuits, data converters, power supplies, and industrial control systems.

Application Scenarios & Design Considerations

Precision Micropower Shunt Voltage Reference 3-SOT-23 -40 to 125

Alternative Part Number

  • LM4051CIM3-1.2 --: Same 1.2V precision shunt voltage reference in SOT-23, functionally equivalent to the TL4051 series with similar accuracy and operating current.
  • LM4041CIM3-1.2 --: 1.2V precision micropower shunt reference in SOT-23, a common drop-in alternative with comparable tolerance and temperature behavior.
  • ADR512ARTZ-REEL7 --: 1.2V high-precision shunt voltage reference in SOT-23, suitable as a cross-manufacturer alternative when tighter initial accuracy is acceptable.
