Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-SOT -40 to 125 The TPS79913DDCR 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:** 1.3 V (fixed)  
- **Output Current:** 50 mA  
- **Dropout Voltage:** 110 mV (typical at 50 mA load)  
- **Input Voltage Range:** 1.7 V to 5.5 V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 17 µA (typical)  
- **Package:** SOT-23-5 (DDC)  

### **Descriptions:**
- The TPS79913DDCR is a low-dropout linear regulator designed for low-power applications.  
- It provides a fixed 1.3 V output with high accuracy (±1.5%).  
- Features low noise and high PSRR (Power Supply Rejection Ratio), making it suitable for noise-sensitive applications.  
- Includes thermal shutdown and current limit protection.  

### **Features:**
- **Ultra-Low Quiescent Current:** 17 µA (typical) for improved battery life.  
- **Low Dropout Voltage:** 110 mV at 50 mA load.  
- **High PSRR:** 60 dB at 1 kHz for noise-sensitive circuits.  
- **Stable with Ceramic Capacitors:** Requires only a 1 µF output capacitor.  
- **Thermal Shutdown & Current Limit Protection:** Ensures safe operation.  
- **Small Package:** SOT-23-5 (DDC) for space-constrained designs.  

This information is based solely on TI's official datasheet for the TPS79913DDCR.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LP5907MFX-1.3/NOPB --: Low-noise 1.3V LDO in SOT-23-5 with similar dropout and current capability, pin-compatible in function and widely available.
  • MIC5504-1.3YM5-TR --: 1.3V fixed LDO in SOT-23-5 offering comparable output current and low quiescent current, suitable drop-in functional replacement.
  • AP2112K-1.3TRG1 --: 1.3V LDO regulator in SOT-23-5 with 600mA capability and low dropout, a cost-effective alternative from a different series.
