LR6232B33M from LRC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin; the datasheet gives an operating supply range of 1.8V to 8V and an absolute maximum input voltage of -0.3V to 9V. |
| 2 | VSS | power_in | Ground pin, the network ground reference for all voltages in the datasheet. |
| 3 | CE | input | Chip enable pin, active high per the B order option; CE high requires 1.5V to VIN and CE low is 0.3V maximum, with standby current of 0.1µA when CE=VSS. |
| 4 | NC | unconnected | No connection pin. |
| 5 | VOUT | power_out | Regulated output pin, adjustable in the 1.2V to 5.0V range with up to 300mA output current; absolute maximum output voltage is VIN+0.3V. |
