Dual-output 1A/2A Low Dropout (LDO) with dual enables and SVS for split-voltage systems 24-HTSSOP -40 to 125 The TPS70402PWPR is a dual-output low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage Options:** Fixed 3.3V and 1.8V (other variants available).
- **Output Current:** 1A (for 3.3V output) and 2A (for 1.8V output).
- **Input Voltage Range:** 2.7V to 5.5V.
- **Dropout Voltage:** 350mV (typical) at 2A load.
- **Accuracy:** ±2% over line, load, and temperature.
- **Quiescent Current:** 85µA (typical) per regulator.
- **Operating Temperature Range:** -40°C to +125°C.
- **Package:** 20-pin HTSSOP (PowerPAD™).

### **Descriptions:**
- Dual-output LDO regulator with independent enable pins.
- Designed for applications requiring multiple voltage rails with high efficiency.
- Includes power-good (PG) indicators for both outputs.
- Features thermal shutdown and overcurrent protection.

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.
- **Fast Transient Response:** Suitable for dynamic load conditions.
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥10µF).
- **Sequencing Capability:** Independent enable pins allow flexible power-up/down sequencing.
- **Power-Good Indicators:** Monitors output status for system reliability.
- **Thermal Shutdown & Overcurrent Protection:** Enhances device safety.

This device is commonly used in DSPs, FPGAs, and other multi-voltage digital systems.
