LT3024EDE#TRPBF from Analog Devices, in a DFN-12-EP(3x4). 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 | BYP1 | passive | Bypass pin for Output 1 reference, clamped internally to ±0.6V; a capacitor up to 0.01μF from OUT1 lowers noise to 20μVRMS, and it must be left unconnected if not used. |
| 2 | OUT1 | power_out | Output 1 supplying up to 500mA to the load, requiring a minimum 3.3μF output capacitor to prevent oscillations. |
| 3 | OUT1 | power_out | Output 1 supplying up to 500mA to the load, requiring a minimum 3.3μF output capacitor to prevent oscillations (tied with pin 2). |
| 4 | GND | power_in | Ground pin, common to both regulators. |
| 5 | OUT2 | power_out | Output 2 supplying up to 100mA to the load, requiring a minimum 1μF output capacitor to prevent oscillations. |
| 6 | BYP2 | passive | Bypass pin for Output 2 reference, clamped internally to ±0.6V; a capacitor up to 0.01μF from OUT2 lowers noise to 20μVRMS, and it must be left unconnected if not used. |
| 7 | ADJ2 | input | Error amplifier input for Output 2, internally clamped to ±7V, regulated to 1.22V with 30nA bias current flowing into the pin, setting an output range of 1.22V to 20V. |
| 8 | SHDN2 | input | Shutdown control for Output 2 that turns the output off when pulled low, must be connected to VIN if unused, and the device will not function if left unconnected. |
| 9 | IN | power_in | Input supply pin common to both regulators, operating from 1.8V to 20V, with a 1μF to 10μF bypass capacitor advised and reverse-voltage protection. |
| 10 | IN | power_in | Input supply pin common to both regulators, operating from 1.8V to 20V, with a 1μF to 10μF bypass capacitor advised and reverse-voltage protection (tied with pin 9). |
| 11 | SHDN1 | input | Shutdown control for Output 1 that turns the output off when pulled low, must be connected to VIN if unused, and the device will not function if left unconnected. |
| 12 | ADJ1 | input | Error amplifier input for Output 1, internally clamped to ±7V, regulated to 1.22V with 30nA bias current flowing into the pin, setting an output range of 1.22V to 20V. |
| 13 | GND | power_in | Exposed pad connected to ground, which must be soldered to PCB ground for optimum thermal performance. |
