Description and Introduction

1.5A/ Low Noise/ Fast Transient Response LDO Regulators The LT1963AES8-1.8 is a low dropout (LDO) linear regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 1.5A  
- **Dropout Voltage:** 340mV (typical at full load)  
- **Input Voltage Range:** 2.3V to 20V  
- **Quiescent Current:** 1mA (typical)  
- **Load Regulation:** 0.02% (typical)  
- **Line Regulation:** 0.02% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC (ES8)  

### **Features:**  
- Low dropout voltage (340mV at 1.5A)  
- Low noise output (30μVRMS typical)  
- Fast transient response  
- Adjustable output (though this variant is fixed at 1.8V)  
- Reverse-battery protection  
- Current limit and thermal shutdown protection  
- Stable with low-ESR ceramic capacitors (≥10μF)  

This regulator is designed for high-performance applications requiring precise voltage regulation with minimal power dissipation.

Application Scenarios & Design Considerations

1.5A/ Low Noise/ Fast Transient Response LDO Regulators

Alternative Part Number

  • TPS7A4718 --: Low-noise 1.8V LDO with similar dropout and current capability, pin-compatible in many designs and widely available.
  • ADP1741 --: 1.8V low-dropout regulator with comparable noise and load regulation, suitable drop-in replacement for LDO applications.
  • MIC29152 --: Adjustable/1.8V-capable LDO with similar current rating and thermal performance, commonly used as an alternative in power supply designs.
