Description and Introduction

Cap-Free, NMOS, 150mA Low Dropout Regulator with Reverse Current Protection 5-SOT-23 -40 to 125 The TPS731125DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.25V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical at 100mA load)  
- **Input Voltage Range:** 1.7V to 5.5V  
- **Accuracy:** ±1% (typical)  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 65dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS731125DBVT is a low-quiescent-current LDO regulator designed for battery-powered applications. It provides a stable 1.25V output with high accuracy and low noise, making it suitable for powering sensitive analog and digital circuits.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with low input voltages.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF (or larger) output capacitor.  
- **Enable Pin (EN):** Allows for power-saving mode when disabled.  

This regulator is commonly used in portable electronics, IoT devices, and power-sensitive applications.
