Description and Introduction

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection 5-SOT-23 -40 to 125 The TPS73219DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.9V (fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 110mV (typical) at 250mA  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 500µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- **Low Dropout:** Optimized for low input-to-output voltage differential.  
- **High PSRR:** 60dB at 1kHz for noise-sensitive applications.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF (or larger) output capacitor.  
- **Thermal and Overcurrent Protection:** Built-in safeguards against overheating and excessive current.  
- **Enable Pin:** Allows for power-saving mode when disabled.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  

This LDO is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications.
