Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LE45CD is a part manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (ST)  
- **Part Number:** LE45CD  
- **Type:** Low-dropout (LDO) voltage regulator  
- **Output Voltage:** Fixed or adjustable (specific value depends on variant)  
- **Output Current:** Up to 450 mA (typical for LE45 series)  
- **Dropout Voltage:** Low dropout (typically < 0.5V at full load)  
- **Input Voltage Range:** Varies by model (e.g., up to 18V for some variants)  
- **Operating Temperature Range:** Typically -40°C to +125°C  
- **Package:** SOT-223 or similar surface-mount package  

### **Descriptions:**  
- The LE45CD is part of ST’s LE45 series of LDO regulators, designed for stable voltage regulation with low power dissipation.  
- It is suitable for battery-powered applications, portable devices, and embedded systems requiring efficient power management.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Optimized for power-sensitive applications.  
- **Overcurrent & Thermal Protection:** Built-in safeguards against excessive current and overheating.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise and ripple in sensitive circuits.  

For exact parameters, refer to the official STMicroelectronics datasheet for the LE45CD variant.
