GONGMOSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8
GM12041ARDZ-3.3-R7 from GONGMOSEMI, in a SOIC-8. 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 | OUT | power_out | Regulated output; place a 10µF or larger ceramic capacitor between OUT and GND as close to the pin as possible, with ESR no more than 3Ω, to keep the regulator stable and prevent oscillation. |
| 2 | SENSE/ADJ | input | Feedback pin to the error amplifier; it is the SENSE pin on fixed-output versions, and on adjustable versions the ADJ pin sits at 1.21V relative to GND with an external output range of 1.21V to 20V. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | NC | unconnected | Not connected. |
| 5 | SHDN | input | Shutdown pin; pull high to enable the device and pull low to disable it, and if the enable function is not needed it must be connected to IN. |
| 6 | GND | power_in | Ground reference pin. |
| 7 | GND | power_in | Ground reference pin. |
| 8 | IN | power_in | Input pin with an input supply range of 1.9V to 20V; a 10µF or larger ceramic capacitor (7µF or larger acceptable) from IN to GND is required to lower input impedance, placed as close to the pin as possible. |
