Description and Introduction

150mA, LDO Regulator, Ultra-Low Power, Iq 500nA w/ Pin-Selectable, Dual-Level Output Voltage 5-SOT -40 to 125 The TPS78001DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 150mA  
- **Input Voltage Range:** 1.7V to 5.5V  
- **Dropout Voltage:** 110mV (typical) at 150mA load  
- **Quiescent Current:** 1µA (typical)  
- **Package:** SOT-23-5 (DDC)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% over line, load, and temperature  
- **Enable Pin:** Yes (active high)  

### **Descriptions:**  
The TPS78001DDCR is an ultra-low-power LDO regulator designed for battery-powered applications. It provides a stable 1.8V output with very low quiescent current, making it suitable for power-sensitive devices like IoT sensors, wearables, and portable electronics.  

### **Features:**  
- **Ultra-Low Quiescent Current:** 1µA (typical) for extended battery life.  
- **Low Dropout Voltage:** 110mV at full load for efficient operation.  
- **Wide Input Voltage Range:** Supports 1.7V to 5.5V input.  
- **High PSRR:** 60dB at 1kHz for noise-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Ensures safe operation.  
- **Small Package:** SOT-23-5 for space-constrained designs.
