Description and Introduction

VERY LOW DROP VOLTAGE REGULATOR WITH INHIBIT The **L4931CPT50-TR** is a low-dropout (LDO) voltage regulator manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **STMicroelectronics (ST)**  

### **Specifications:**  
- **Output Voltage:** 5.0V  
- **Output Current:** 250mA  
- **Dropout Voltage:** 0.4V (typical at full load)  
- **Input Voltage Range:** Up to 28V  
- **Quiescent Current:** 1.5mA (typical)  
- **Low Standby Current:** 0.1µA (typical in OFF mode)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** **TO-252-3 (DPAK)**  

### **Descriptions & Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Reduces power consumption in active mode.  
- **Very Low Standby Current:** Ideal for battery-powered applications.  
- **Thermal Protection:** Built-in thermal shutdown prevents overheating.  
- **Short-Circuit Protection:** Safeguards against output short circuits.  
- **Reverse Polarity Protection:** Protects the device if the input voltage is reversed.  
- **Enable Function:** Allows the regulator to be turned ON/OFF via an external logic signal.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

### **Applications:**  
- Automotive systems  
- Industrial controls  
- Battery-powered devices  
- Portable electronics  

This information is based on STMicroelectronics' official datasheet for the **L4931CPT50-TR**.
