Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; the datasheet recommends connecting GND to a heat spreading plane. |
| 2 | VIN | power_in | Input supply voltage; for the RS3112-2.048 the minimum is 2.45 V, the recommended maximum is 5 V, and the absolute maximum is 5.5 V. |
| 3 | NC | unconnected | No internal connection; the datasheet recommends connecting GND to a heat spreading plane. |
| 4 | GND | power_in | Ground reference; all voltages are specified with respect to the GND pin. |
| 5 | NC | unconnected | No internal connection; the datasheet recommends connecting GND to a heat spreading plane. |
| 6 | OUT | output | Reference output voltage, rated for a load current of -10 mA to 10 mA with output short-circuit limits of -30 mA to 30 mA, and requires a minimum 1 µF capacitor from VOUT to GND. |
| 7 | NC | unconnected | No internal connection; the datasheet recommends connecting GND to a heat spreading plane. |
| 8 | NC | unconnected | No internal connection; the datasheet recommends connecting GND to a heat spreading plane. |
