- **Output Current:**  
  - 1A on the first channel (5V).  
  - 2A on the second channel (3.3V).  
- **Input Voltage Range:**  
  - 2.7V to 5.5V.  
- **Dropout Voltage:**  
  - 200mV (typical) at 1A for the 5V output.  
  - 180mV (typical) at 2A for the 3.3V output.  
- **Accuracy:**  
  - ±2% over line, load, and temperature.  
- **Power-On Reset (POR) Delay:**  
  - Adjustable via external capacitor.  
- **Package:**  
  - 20-pin HTSSOP (PW) with PowerPAD™ (PWPR).  
- **Operating Temperature Range:**
