Description and Introduction

Ultra Low-Power 50-mA Low-Dropout (LDO) Linear Regulators The TPS77025DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 175mV (typical at 150mA load)  
- **Input Voltage Range:** 2.7V to 10V  
- **Quiescent Current:** 17µA (typical)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions and Features:**  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown and Overcurrent Protection:** Enhances reliability.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors as low as 1µF.  
- **Fast Transient Response:** Suitable for noise-sensitive applications.  
- **Fixed Output Voltage Options:** Available in multiple standard voltages.  

This LDO is commonly used in portable electronics, power-sensitive embedded systems, and battery-powered devices.

Application Scenarios & Design Considerations

Ultra Low-Power 50-mA Low-Dropout (LDO) Linear Regulators

Alternative Part Number

  • LP2985AIM5-2.5 --: Low-dropout 2.5V linear regulator in SOT-23-5 with similar current capability and pinout, a common drop-in alternative from the same vendor.
  • MIC5205-2.5YM5 --: 2.5V LDO regulator in SOT-23-5 with comparable dropout and output current, widely used as a cross-vendor substitute.
  • AP2112K-2.5TRG1 --: 2.5V CMOS LDO in SOT-23-5 offering low quiescent current and stable output, suitable replacement for the TPS77025 family.
  • LP2985AIM5-2.5/NOPB --: Low-dropout 2.5V regulator in SOT-23-5 with similar 150mA output and low quiescent current, pin-compatible footprint for many designs.
  • MIC5205-2.5YM5-TR --: 150mA LDO in SOT-23-5 delivering 2.5V with low dropout and low noise, a common drop-in style replacement from a different series.
