- Continuous output current: up to 1.5 A (when input voltage ≥ output voltage); startup current limited to approx. 700 mA
- Efficiency: 85–95% (typical)
- Enable input (EN) for shutdown with low quiescent current
- Soft start
- No reverse polarity protection
- Pins: VIN, GND, VOUT, EN on a 2.54 mm grid (pin header not included)
- Dimensions: 10.9 × 16.5 × 4.1 mm
