Description and Introduction

200 mA, Low Quiescent Current, Ultra-Low Noise, High PSRR, LDO Linear Regulator for Automotive 6-WSON -40 to 125 The TPS79901QDRVRQ1 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage:** 0.8V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 110mV (typical at 200mA load)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Pin WSON (2mm × 2mm)  

### **Descriptions:**
- Designed for automotive applications (AEC-Q100 qualified).  
- Ultra-low dropout voltage for efficient power management.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Includes thermal shutdown and current limit protection.  

### **Features:**
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response:** Ideal for noise-sensitive applications.  
- **Enable Pin:** Allows power-saving shutdown mode.  
- **Reverse Current Protection:** Prevents damage from reverse voltage conditions.  
- **High PSRR:** 70dB at 1kHz for improved noise rejection.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LP5907MFX-1.2/NOPB --: Low-noise 250 mA LDO in SOT-23-5 with similar dropout and PSRR performance, suitable for automotive-adjacent low-noise rails and pin-compatible in function.
  • MIC5504-1.2YM5-TR --: 300 mA low-dropout regulator in SOT-23-5 with comparable noise and quiescent current, offering a different series and vendor for second-source flexibility.
  • AP2112K-1.2TRG1 --: 600 mA CMOS LDO in SOT-23-5 with wide input range and low dropout, providing higher current headroom and a distinct naming series as a cost-effective alternative.
