Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LF90AB is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** Fixed 9V  
- **Output Current:** Up to 150mA  
- **Dropout Voltage:** Typically 0.4V at full load  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 1.6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-92, SOT-89  

### **Descriptions:**  
- The LF90AB is a fixed-output LDO regulator designed for low-power applications.  
- It provides stable voltage regulation with low noise and high ripple rejection.  
- Suitable for battery-powered devices, automotive systems, and industrial controls.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Protection:** Built-in thermal shutdown prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the regulator and connected circuitry.  
- **Low Quiescent Current:** Enhances power efficiency in standby modes.  
- **Wide Input Voltage Range:** Supports operation in various power supply conditions.
