Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121CN8 is a low dropout (LDO) linear regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable from 3.75V to 30V or fixed 5V, 12V, and 15V options.
- **Output Current:** 150mA (guaranteed).
- **Dropout Voltage:** 0.4V typical at full load (150mA).
- **Input Voltage Range:** Up to 30V.
- **Line Regulation:** 0.0005%/V typical.
- **Load Regulation:** 0.002%/mA typical.
- **Quiescent Current:** 1.5mA typical (3mA max).
- **Operating Temperature Range:** -40°C to +125°C.
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package).

### **Descriptions:**
- The LT1121CN8 is a high-performance, low dropout linear regulator designed for applications requiring stable and precise voltage regulation.
- It features low dropout voltage, making it suitable for battery-powered and power-sensitive systems.
- The device includes thermal shutdown and current limit protection for enhanced reliability.

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.
- **Adjustable Output:** Allows flexibility in setting the desired output voltage (for adjustable versions).
- **High Accuracy:** Tight line and load regulation for stable output.
- **Thermal Shutdown:** Protects the device from overheating.
- **Current Limit Protection:** Safeguards against excessive load currents.
- **Wide Input Voltage Range:** Supports a broad range of input sources.
- **Low Quiescent Current:** Minimizes power loss in standby modes.
