Output voltage | Typical max current output* | Input voltage range | Size |
---|---|---|---|
9 V | 2 A | 3 V – 30 V | 0.825″ × 1.7″ |
*For input voltages close to the output. Actual achievable maximum continuous current is a function of input and output voltage and is limited by thermal dissipation. See the output current graphs on the product page for more information.

Notes:
- 1
- Without included optional headers or terminal blocks. Height with terminal blocks installed is approximately 0.5″.
- 2
- Without included optional headers or terminal blocks. Terminal blocks add 3.4 g.
- 3
- Absolute maximum. Recommended maximum operating voltage is 30 V, and reverse voltage protection only works up to 30 V.
- 4
- Under typical conditions, where the input voltage is close to the output voltage. Maximum output current can be higher when stepping down and lower when stepping up.
- 5
- For input voltages up to 30 V.
- 6
- Typical worst case (i.e. with VIN at 3 V). Quiescent current depends on the input and output voltages and is much lower for most of the input voltage range. The ENABLE pin can be used to reduce the quiescent current to well under 1 mA.
