Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 6-WSON -40 to 125 The TPS79901DRVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 0.8V (fixed)  
- **Output Current:** 50mA  
- **Dropout Voltage:** 110mV (typical at 50mA load)  
- **Input Voltage Range:** 1.7V to 5.5V  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DRV)  

### **Descriptions:**  
The TPS79901DRVT is an ultra-low-power LDO regulator designed for battery-powered applications. It provides a stable 0.8V output with low noise and high PSRR, making it suitable for noise-sensitive analog and digital circuits.  

### **Features:**  
- Ultra-low quiescent current (17µA typical)  
- Low dropout voltage (110mV at 50mA)  
- Stable with ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Small SOT-23-5 package for space-constrained designs  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 6-WSON -40 to 125

Alternative Part Number

  • LP5907MFX-1.2/NOPB --: Low-noise LDO in a different series with similar 250 mA output and adjustable/fixed options, good drop-in for low-noise analog rails.
  • MIC5504-1.2YM5-TR --: Small 300 mA LDO with low quiescent current in SOT-23-5, a practical alternative when the WSON package is not required.
  • AP2112K-1.2TRG1 --: 600 mA CMOS LDO with wide input range and low dropout, suitable replacement for general 1.2 V regulation needs.
