Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-SOT -40 to 125 The TPS79912DDCTG4 is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.2V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 175mV (typical) at 200mA  
- **Input Voltage Range:** 2.2V to 6.5V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Enable Threshold:** 1.5V (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DDC)  

### **Descriptions:**
- The TPS79912DDCTG4 is a low-power, high-performance LDO regulator designed for battery-powered and portable applications.  
- It provides a stable 1.2V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features an enable pin for power management and thermal shutdown protection.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Ultra-Low Quiescent Current:** Extends battery life in portable devices.  
- **High PSRR:** 70dB at 1kHz (improves noise immunity).  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Ceramic Capacitors:** Reduces board space and cost.  
- **Fast Transient Response:** Suitable for dynamic load applications.  

This regulator is commonly used in portable electronics, medical devices, and industrial applications requiring precise voltage regulation.
