Description and Introduction

ULTRA LOW DROP-LOW NOISE BICMOS VOLTAGE REGULATORS LOW ESR CAPACITORS COMPATIBLE The LD3985J26R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Output Voltage:** 2.6V (fixed)  
- **Output Current:** Up to 150mA  
- **Dropout Voltage:** Typically 200mV at 100mA load  
- **Input Voltage Range:** 2.7V to 6V  
- **Low Quiescent Current:** 50µA (typical)  
- **High PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Low Noise:** 30µV RMS (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Features:**  
- **Ultra-Low Dropout:** Ensures stable output even with small input-output differential.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Thermal Shutdown & Current Limitation:** Built-in protection features.  
- **Fast Start-Up Time:** Suitable for power-sensitive applications.  

The LD3985J26R is commonly used in portable devices, IoT applications, and power management circuits requiring stable voltage regulation.
