Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LF90ABPT-TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Part Number:** LF90ABPT-TR  
- **Type:** Low-Dropout (LDO) Voltage Regulator  
- **Output Voltage:** 9V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 0.4V (typical at 500mA)  
- **Input Voltage Range:** Up to 20V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252-3 (DPAK)  
- **Mounting Type:** Surface Mount  
- **Protection Features:** Overcurrent, Thermal Shutdown  

### **Descriptions:**  
The LF90ABPT-TR is a fixed-output LDO regulator designed for applications requiring stable and efficient voltage regulation. It provides a 9V output with a maximum current of 500mA and features low dropout voltage, making it suitable for battery-powered and space-constrained systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even when the input voltage is close to the output.  
- **High Accuracy:** Tight output voltage tolerance (±2%).  
- **Thermal Protection:** Built-in thermal shutdown prevents damage from overheating.  
- **Overcurrent Protection:** Safeguards against excessive current draw.  
- **Wide Input Voltage Range:** Supports up to 20V input.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is based on STMicroelectronics' official documentation for the LF90ABPT-TR.
