Description and Introduction

Ultralow-Noise, High-PSRR, Fast, RF, 1.5-A Low-Dropout Linear Regulators 6-SOT-223 -40 to 125 The TPS78601DCQRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable (1.2V to 5.5V) or fixed options available.  
- **Output Current:** Up to 1.5A.  
- **Dropout Voltage:** 340mV typical at full load (1.5A).  
- **Input Voltage Range:** 2.7V to 6.5V.  
- **Accuracy:** ±1.5% over line, load, and temperature.  
- **Quiescent Current:** 1mA typical (reduces to <1µA in shutdown).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Package:** 6-pin SON (DRC) or 8-pin SOIC (D).  

### **Descriptions:**
- The TPS78601 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.  
- It features a low-dropout voltage, making it suitable for battery-powered and portable devices.  
- The adjustable version allows flexibility in setting the output voltage via external resistors.  

### **Features:**
- **High PSRR:** 75dB at 1kHz.  
- **Low Noise:** 30µVRMS (10Hz to 100kHz).  
- **Fast Transient Response:** Excellent line and load regulation.  
- **Thermal and Overcurrent Protection:** Built-in safeguards.  
- **Enable Pin:** Allows shutdown mode for power saving.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces BOM cost.  

This regulator is commonly used in power-sensitive applications such as DSPs, FPGAs, and wireless communication systems.
