Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LE33ABD is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 150mA  
- **Input Voltage Range:** 2.5V to 10V  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 1.5µA (typical in OFF mode), 50µA (typical in ON mode)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT23-5  

### **Descriptions:**  
- The LE33ABD is a low-power LDO regulator designed for battery-powered applications.  
- It provides a stable 3.3V output with low dropout voltage, making it suitable for systems with tight voltage margins.  
- Features an enable (ON/OFF) pin for power-saving modes.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the device during fault conditions.  
- **Enable Pin:** Allows shutdown mode for reduced power consumption.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors for compact designs.  

This information is based on the manufacturer's datasheet for the LE33ABD.
