Description and Introduction

Single Output LDO, 1A, Adj. (1.2 to 5.0V), Reverse Current Protection 6-SOT-223 -40 to 125 The TPS73701DCQ is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** Adjustable (1.2 V to 5.5 V) or fixed options available.  
- **Output Current:** Up to 1 A.  
- **Dropout Voltage:** 210 mV (typical) at 1 A load.  
- **Input Voltage Range:** 2.2 V to 6 V.  
- **Accuracy:** ±1.5% (over line, load, and temperature).  
- **Quiescent Current:** 85 µA (typical).  
- **Package:** 6-pin SOT-223 (DCQ).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Protection Features:** Thermal shutdown, current limit, and reverse current protection.  

### **Descriptions:**  
The TPS73701DCQ is a high-performance LDO regulator designed for applications requiring low noise, high PSRR (Power Supply Rejection Ratio), and fast transient response. It is suitable for powering sensitive analog and digital circuits.  

### **Features:**  
- **Low Dropout:** Enables efficient operation with small input-output differentials.  
- **High PSRR:** 75 dB at 1 kHz (typical).  
- **Low Noise:** 30 µVRMS (typical) with bypass capacitor.  
- **Fast Transient Response:** Ideal for dynamic load conditions.  
- **Stable with Ceramic Capacitors:** Requires only a 2.2 µF output capacitor.  
- **Adjustable and Fixed Voltage Options:** Provides design flexibility.  
- **Thermal Shutdown and Current Limit Protection:** Enhances reliability.

Application Scenarios & Design Considerations

Single Output LDO, 1A, Adj. (1.2 to 5.0V), Reverse Current Protection 6-SOT-223 -40 to 125

Alternative Part Number

  • LP38691SD-ADJ --: Adjustable low-dropout linear regulator in a similar SOT-223 style package with comparable 500 mA current capability and low dropout, suitable as a functional substitute.
  • MIC5219YM5-TR --: Adjustable LDO regulator with low dropout and good noise performance, offering similar functionality for low-voltage applications though with lower current rating.
  • LT1963AEQ#PBF --: Low-noise adjustable LDO regulator with excellent PSRR and stability, a higher-performance alternative when board space and cost allow.
  • LT1963AEQ --: Adjustable low-noise LDO regulator with comparable dropout and current ratings, usable as an alternative when TI parts are unavailable.
