Description and Introduction

1.5A, Low Noise, Fast Transient Response LDO Regulators The LT1963AEFE-2.5#PBF is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 1.5A  
- **Dropout Voltage:** 340mV (typical at full load)  
- **Input Voltage Range:** 2.7V to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (FE)  

### **Descriptions:**  
- The LT1963AEFE-2.5#PBF is a high-performance LDO regulator designed for applications requiring low noise and high efficiency.  
- It features fast transient response and stable operation with low ESR capacitors.  
- Includes protection features such as current limit, thermal shutdown, and reverse-battery protection.  

### **Features:**  
- Low dropout voltage (340mV typical at 1.5A)  
- Low noise (40µVRMS typical)  
- Adjustable output (fixed 2.5V version)  
- Stable with ceramic capacitors  
- Reverse battery protection  
- Current limit and thermal shutdown  
- Low quiescent current in shutdown mode  

This regulator is commonly used in power-sensitive applications such as battery-powered devices, instrumentation, and RF systems.

Application Scenarios & Design Considerations

1.5A, Low Noise, Fast Transient Response LDO Regulators

Alternative Part Number

  • TPS7A4525KTTR --: Low-noise 2.5V LDO with similar current capability and thermal performance, widely available and pin-compatible in function.
  • ADP3338AKC-2.5-RL --: 2.5V low-dropout regulator with comparable noise and load regulation, suitable drop-in functional replacement.
  • MIC29302WU --: Adjustable high-current LDO that can be set to 2.5V, offering robust thermal and current headroom as a fallback option.
