Description and Introduction

Dual-output (3.3V/1.8V)1A/2A LDO Regulator with dual enables and SVS for split-voltage systems 24-HTSSOP -40 to 125 The TPS70451PWP is a dual-output voltage regulator manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage 1 (Fixed):** 5V  
- **Output Voltage 2 (Adjustable):** 1.2V to 5.5V  
- **Output Current:** 1A (each channel)  
- **Dropout Voltage:** 350mV (typical) at 1A  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 85µA (per channel, typical)  
- **Switching Frequency:** 550kHz (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** HTSSOP-24 (PWP)  

### **Descriptions:**  
The TPS70451PWP is a dual-output, low-dropout (LDO) voltage regulator designed for applications requiring multiple regulated voltages. It integrates two independent regulators with high efficiency and low quiescent current, making it suitable for battery-powered devices.  

### **Features:**  
- **Dual Independent LDO Regulators** (5V fixed and adjustable output)  
- **Low Dropout Voltage** (350mV typical at 1A)  
- **High PSRR** (Power Supply Rejection Ratio)  
- **Low Quiescent Current** (85µA per channel)  
- **Thermal and Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  
- **Power-Good Output for Monitoring**  
- **Small HTSSOP-24 Package**  

This information is based on TI's official datasheet for the TPS70451PWP.
