Description and Introduction

Ultralow-Power, Low-Noise 50-mA Low Dropout (LDO) Linear Regulator The TPS79030DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 150mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Dropout Voltage:** 120mV (typical at 150mA)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR:** 70dB at 1kHz  

### **Descriptions and Features:**  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Low Dropout:** Suitable for battery-powered applications  
- **High PSRR:** Ensures stable output under varying input conditions  
- **Thermal & Overcurrent Protection:** Enhances reliability  
- **Enable Pin:** Allows power-saving mode when disabled  
- **Stable with Ceramic Capacitors:** No need for additional ESR  

This LDO is designed for portable and power-sensitive applications such as battery-powered devices, medical equipment, and industrial systems.

Application Scenarios & Design Considerations

Ultralow-Power, Low-Noise 50-mA Low Dropout (LDO) Linear Regulator

Alternative Part Number

  • LP2985AIM5-3.0 --: Low-dropout 3.0V linear regulator in SOT-23-5 with similar current capability and pin-compatible function, widely available and often used as a drop-in substitute.
  • MIC5205-3.0YM5 --: 3.0V LDO regulator in SOT-23-5 with comparable dropout and output current, from a different vendor and series for easy distinction.
  • AP2112K-3.0TRG1 --: 3.0V CMOS LDO in SOT-23-5 offering similar performance and low quiescent current, suitable as an alternative from a different manufacturer.
