Description and Introduction

Low-Noise, High PSRR, RF 200-mA Low-Dropout Linear Regulators The TPS73030DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 150mA load  
- **Input Voltage Range:** 1.7V to 5.5V  
- **Quiescent Current:** 20µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TPS73030DBVT is a low-noise, low-dropout linear regulator designed for battery-powered and portable applications.  
- It provides a stable 3.0V output with high accuracy (±1.5%).  
- Features an enable pin (EN) for power management.  
- Stable with low-ESR ceramic capacitors (≥1µF).  

### **Features:**  
- **Ultra-Low Dropout:** 110mV at 150mA load  
- **Low Noise:** Optimized for noise-sensitive applications  
- **Low IQ:** 20µA typical quiescent current  
- **Thermal & Overcurrent Protection:** Built-in safety features  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Low-Noise, High PSRR, RF 200-mA Low-Dropout Linear Regulators

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 cost-effective.
  • MIC5205-3.0YM5 --: 3.0V LDO regulator in SOT-23-5 offering comparable dropout and output current, suitable drop-in replacement for many TPS73030 applications.
  • AP2112K-3.0TRG1 --: 3.0V CMOS LDO in SOT-23-5 with low quiescent current and good stability, a practical alternative when TI parts are unavailable.
