Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-DSBGA -40 to 125 The TPS79932YZUR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.2V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 110mV (typical) at 200mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Enable Threshold:** 1.5V (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Pin SOT-23 (YZUR)  

### **Descriptions:**
- The TPS79932YZUR is a low-power, high-performance LDO regulator designed for battery-powered and noise-sensitive applications.  
- It provides a stable 3.2V output with low dropout and low quiescent current, making it suitable for portable devices.  
- Features reverse current protection and thermal shutdown for enhanced reliability.  

### **Features:**
- **Ultra-Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications like RF and analog circuits.  
- **Fast Transient Response:** Maintains stable output under dynamic load conditions.  
- **Thermal Shutdown & Overcurrent Protection:** Protects the device from damage.  
- **Reverse Current Protection:** Prevents current flow from output to input.  
- **Small Form Factor:** SOT-23 package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-DSBGA -40 to 125

Alternative Part Number

  • LP5907MFX-3.2/NOPB --: Low-noise 250 mA LDO in SOT-23-5 with fixed 3.2 V output, functionally similar to the TPS79932 and widely available.
  • TLV70232PDBVR --: 300 mA low-dropout regulator with 3.2 V fixed output in SOT-23-5, good drop-in style alternative for space-constrained designs.
  • MIC5219-3.2YM5-TR --: 500 mA LDO regulator with 3.2 V output in SOT-23-5, offers higher current capability and comes from a different vendor for supply flexibility.
  • AP2112K-3.2TRG1 --: 600 mA CMOS LDO with 3.2 V output in SOT-23-5, low quiescent current and a common alternative for small 3.2 V rail designs.
