GM1204AHZ-RL from GONGMOSEMI, in a TO-263-5. 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 | SHDN | input | Shutdown pin: pull high to enable the device and pull low to disable it, and it must be connected to IN if the enable function is not needed; its absolute maximum rating to GND is -0.3 V to +22 V. |
| 2 | IN | power_in | Input pin with an input operating range of 1.9 V to 20 V, requiring a 10 µF or larger ceramic capacitor (7 µF or more) from IN to GND placed as close to the pin as possible; absolute maximum rating to GND is -0.3 V to +22 V. |
| 3 | GND | power_in | Ground pin. |
| 4 | OUT | power_out | Regulated output pin that requires a 10 µF or larger ceramic capacitor to GND placed as close to the pin as possible for stability, with absolute maximum rating to GND of -0.3 V to +22 V. |
| 5 | SENSE/ADJ | input | Feedback pin to the error amplifier: SENSE is used for fixed-output versions, while ADJ sits at 0.9 V, 1.0 V, 1.1 V or 1.21 V relative to GND for adjustable output up to 20 V, with absolute maximum rating to GND of -0.3 V to +6 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
