Description and Introduction

1.2A Integrated FETs, High Efficiency Synchronous Buck Regulator The ISL8011IRZ-T is a low-dropout (LDO) voltage regulator manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to 5V (fixed versions also available)  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** 200mV (typical) at 1A load  
- **Quiescent Current:** 85μA (typical)  
- **Load Regulation:** ±0.3% (typical)  
- **Line Regulation:** ±0.05% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead DFN (3mm x 3mm)  

### **Descriptions:**  
- The ISL8011IRZ-T is a high-performance, low-dropout linear regulator designed for applications requiring low noise and high efficiency.  
- It features a low quiescent current, making it suitable for battery-powered devices.  
- The adjustable output version allows flexibility in setting the desired voltage via external resistors.  

### **Features:**  
- **Low Dropout Voltage:** Ensures stable operation even with small input-output differentials.  
- **Low Noise & High PSRR:** Suitable for noise-sensitive applications like RF and analog circuits.  
- **Fast Transient Response:** Maintains stability under dynamic load conditions.  
- **Overcurrent & Thermal Protection:** Safeguards the device and system from damage.  
- **Enable Pin:** Allows for power management control.  
- **Stable with Ceramic Capacitors:** Reduces board space and cost.  

This information is strictly based on the manufacturer's datasheet and does not include any additional recommendations or guidance.

Application Scenarios & Design Considerations

1.2A Integrated FETs, High Efficiency Synchronous Buck Regulator

Alternative Part Number

  • TPS62130RGTR --: Pin-compatible 3A step-down converter with similar input range and adjustable output, widely available and a strong functional drop-in for the ISL8011IRZ-T.
  • LMR33630ADDA --: 3A synchronous buck regulator in an SOIC-style package offering comparable efficiency and current capability, suitable as a direct replacement with minor layout adjustment.
  • MP2315GJ-Z --: Compact 3A synchronous step-down converter with similar voltage ratings and low external component count, a cost-effective alternative for the same application.
  • MP1584EN --: Low-cost 3A synchronous buck converter covering the same input/output range, suitable drop-in for many ISL8011 designs.
  • LMR14030SDDAR --: 3A 40V buck regulator with integrated MOSFET, similar switching frequency and thermal performance, good second-source option.
