LN1152B122MR-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, operating range 2.0 V to 7 V, with absolute maximum rating VSS−0.3 V to VSS+8 V. |
| 2 | VSS | power_in | Ground pin, the reference for all absolute maximum ratings (VIN, VOUT and CE are specified relative to VSS). |
| 3 | CE | input | Enable input; the B-option of this MPN is active-high with a built-in pull-down resistor, minimum high level 1.6 V, maximum low level 0.5 V, and absolute maximum VSS−0.3 V to VIN+0.3 V. |
| 4 | NC | unconnected | No connection (listed as 空, empty, in the datasheet pin table). |
| 5 | VOUT | power_out | Regulated output pin, absolute maximum VSS−0.3 V to VIN+0.3 V, with output current up to 500 mA when VIN ≥ VOUT+1 V. |
