Description and Introduction

Dual Output LNB Supply and Control Voltage Regulator with I2C Interface for Advanced Satellite Set-Top Box Designs The ISL6422BERZ is a dual LDO (Low Dropout) regulator manufactured by INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.85V to 6.5V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V (for each regulator)  
- **Output Current:** Up to 300mA per channel  
- **Dropout Voltage:** 300mV (typical) at full load  
- **Quiescent Current:** 60µA (typical) per channel  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead DFN (3mm x 3mm)  

### **Descriptions:**
- The ISL6422BERZ is a dual, high-performance LDO regulator designed for applications requiring low noise and high PSRR (Power Supply Rejection Ratio).  
- It features independent enable controls for each regulator, allowing flexible power management.  
- The device is optimized for battery-powered systems, portable electronics, and point-of-load regulation.  

### **Features:**
- **Dual Independent LDOs:** Two adjustable regulators in a single package.  
- **Low Dropout Voltage:** 300mV typical at full load.  
- **High PSRR:** >70dB at 1kHz (for noise-sensitive applications).  
- **Low Quiescent Current:** 60µA per channel (enhances battery life).  
- **Adjustable Output Voltage:** Set via external resistors (0.8V to 5.5V).  
- **Thermal Shutdown & Current Limit Protection:** Prevents damage from overheating or overcurrent.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Stable with Ceramic Capacitors:** Reduces cost and board space.  

This information is based on the manufacturer's datasheet and technical documentation.
