Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN1 | input | 1-Channel enable input; EN high level is 1.2V min and EN low level is 0.3V max, and pulling EN to VSS shuts channel 1 down and discharges CL through the typ. 160Ω auto-discharge resistance. |
| 2 | VIN | power_in | Voltage input with a 1.6V to 6.0V operating range; absolute maximum input voltage is -0.3V to +7.0V. |
| 3 | EN2 | input | 2-Channel enable input; EN high level is 1.2V min and EN low level is 0.3V max, and pulling EN to VSS shuts channel 2 down and discharges CL through the typ. 160Ω auto-discharge resistance. |
| 4 | VOUT2 | power_out | 2-Channel regulated output; VOUT must not exceed VIN+0.3V to avoid reverse current through the parasitic diode, and a ceramic CL of at least 1.0µF is recommended between VOUT2 and VSS. |
| 5 | VSS | power_in | Power ground, the reference for both outputs and the enable levels, and the return for CIN and CL. |
| 6 | VOUT1 | power_out | 1-Channel regulated output; VOUT must not exceed VIN+0.3V to avoid reverse current through the parasitic diode, and a ceramic CL of at least 1.0µF is recommended between VOUT1 and VSS. |
