LN1234B152MR-G from NATLINEAR, in a SOT-23-5L. 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 | Input supply pin; the datasheet gives an operating input voltage of 1.8 V to 5 V and an absolute maximum of -0.3 V to +5 V. |
| 2 | VSS | power_in | Ground pin, the regulator's common reference for the input, output and CE logic. |
| 3 | CE | input | Enable pin; for this CE-logic variant (B) it is active high with no built-in pull-down, with a minimum high level of 1.2 V and a minimum low level of 0.6 V. |
| 4 | NC | unconnected | No connection (marked as empty in the datasheet pin table). |
| 5 | VOUT | power_out | Regulated output pin; this part is set to 1.5 V (order code digits 15) and delivers up to 300 mA at VIN ≥ 2.5 V. |
