Description and Introduction

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection The TPS73225DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 75mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 60dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
- The TPS73225DBVR is a low-noise, high-PSRR LDO regulator designed for precision voltage regulation.  
- It features a fast transient response and stable operation with small ceramic capacitors (≥1µF).  
- Includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**
- **Low Dropout:** 75mV typical at 100mA load.  
- **High PSRR:** 60dB at 1kHz for noise-sensitive applications.  
- **Low Noise:** Optimized for noise-sensitive applications like RF and analog circuits.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF (or larger) output capacitor.  
- **Thermal Shutdown & Current Limit:** Protects the device from overheating and overcurrent.  
- **Enable Pin:** Allows for power-saving modes when disabled.

Application Scenarios & Design Considerations

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection

Alternative Part Number

  • LP2985AIM5-2.5 --: Low-dropout linear regulator with fixed 2.5V output in SOT-23-5, similar current capability and pin-compatible footprint, widely available and cost-effective.
  • MIC5205-2.5YM5 --: 2.5V fixed LDO in SOT-23-5 with low dropout and low quiescent current, suitable drop-in replacement for many 2.5V regulator applications.
  • AP2112K-2.5TRG1 --: 2.5V fixed LDO regulator in SOT-23-5 with good load transient response and low noise, offering a different vendor and series as an alternative.
