GONGMOSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5
GM12042AHZ-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, with SHDN-low input threshold at 0.75 V max and SHDN-high threshold at 0.79 V min, and it must be tied to IN if the enable function is not needed; absolute maximum is -0.3 V to +22 V. |
| 2 | IN | power_in | Input pin with an operating input range of 1.9 V to 20 V, requiring a ceramic capacitor of 10 µF or larger (7 µF or larger minimum) from IN to GND placed as close to the pin as possible; absolute maximum is -0.3 V to +22 V. |
| 3 | GND | power_in | Ground pin. |
| 4 | OUT | power_out | Regulated output pin that requires a ceramic capacitor of 10 µF or larger from OUT to GND placed as close to the pin as possible for stability (ESR at or below 3 Ω is recommended in the layout guidance); absolute maximum is -0.3 V to +22 V. |
| 5 | SENSE/ADJ | input | Feedback pin to the error amplifier: SENSE is used for fixed-output versions, while on the adjustable version the ADJ voltage is 1.21 V or 1.24 V relative to GND with an external output range of 1.21 V or 1.24 V up to 20 V; absolute maximum is -0.3 V to +6 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
