Description and Introduction

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO The TPS79915DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.5V (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)  
- **Package:** SOT-23-5 (DDC)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR:** 75dB at 1kHz  
- **Enable Pin:** Yes (active high)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- **Low Dropout:** Optimized for battery-powered applications.  
- **Low Noise:** High power supply rejection ratio (PSRR) for noise-sensitive applications.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor.  
- **Fast Transient Response:** Suitable for dynamic loads.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Enable Control:** Allows power sequencing and shutdown modes.  

This LDO is commonly used in portable electronics, IoT devices, and power-sensitive applications.

Application Scenarios & Design Considerations

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO

Alternative Part Number

  • LP5907MFX-1.5/NOPB --: Low-noise 1.5V LDO in SOT-23-5 with similar dropout and current capability, pin-compatible in function and widely available.
  • MIC5504-1.5YM5-TR --: 1.5V fixed LDO in SOT-23-5 offering comparable output current and low quiescent current, suitable drop-in functional replacement.
  • AP2112K-1.5TRG1 --: 1.5V CMOS LDO in SOT-23-5 with similar current rating and low dropout, a cost-effective alternative from a different series.
  • MIC5219-1.5YM5-TR --: 1.5V fixed LDO in SOT-23-5 with comparable output current and low dropout, suitable when a different series is preferred.
