## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ICC | passive | Sets the constant-current limit through resistor RICC to GND per ICC = 1188V / RICC, and its voltage (1.18V to 1.23V in constant-current mode) monitors output current in normal operation. |
| 2 | GND | power_in | Ground, the negative terminal for the input supply and output voltage. |
| 3 | VIN | power_in | Input supply positive terminal, supplying 2.7V to 6V to the internal circuits, with a filter capacitor required between VIN and GND. |
| 4 | VIN | power_in | Input supply positive terminal, supplying 2.7V to 6V to the internal circuits, with a filter capacitor required between VIN and GND. |
| 5 | OUT | power_out | Regulated output positive terminal delivering up to 1 A, with a low-ESR filter capacitor required between OUT and GND. |
| 6 | OUT | power_out | Regulated output positive terminal delivering up to 1 A, with a low-ESR filter capacitor required between OUT and GND. |
| 7 | NC | unconnected | No connection. |
| 8 | CE | input | Chip enable input: high level (above 2.2V) enables normal operation and low level (below 0.7V) disables the device, and it can be driven by TTL or CMOS levels. |
| 9 | EP | passive | Exposed heatsink pad that must be soldered to a ground copper area on the PCB for maximum thermal performance and output current. |
