Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121IS8-5 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Quiescent Current:** 1.5mA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions & Features:**  
- **Low Dropout Voltage:** Ensures stable output even with small input-output differentials.  
- **Wide Input Voltage Range:** Supports up to 30V input.  
- **Low Quiescent Current:** Improves efficiency in battery-powered applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Precision Output Voltage:** Tight tolerance (±4%) ensures consistent performance.  

The LT1121IS8-5 is suitable for applications requiring stable, low-noise power supplies, such as portable electronics, industrial systems, and automotive devices.
