LT3021EDH#PBF from Analog Devices, in a DFN-16(5x5). 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 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 2 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 3 | OUT | power_out | Supplies power to the load; requires a minimum output capacitor of 3.3μF to prevent oscillations (pins 3 and 4 are both OUT). |
| 4 | OUT | power_out | Supplies power to the load; requires a minimum output capacitor of 3.3μF to prevent oscillations (pins 3 and 4 are both OUT). |
| 5 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 6 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 7 | ADJ | input | Inverting terminal of the error amplifier with a 200mV reference referred to GND and a typical 20nA bias current flowing out of the pin; output is set by an external resistor divider. |
| 8 | AGND | power_in | Ground; connect directly to the exposed pad and pin 10 for best performance. |
| 9 | SHDN | input | Pulling low turns the output off and puts the device in a low power state; tie to VIN if unused, since the device does not function if SHDN is left unconnected. |
| 10 | PGND | power_in | Ground; connect directly to the exposed pad and pin 8 for best performance. |
| 11 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 12 | IN | power_in | Supplies power to the device (pins 12 and 14 are both IN); a 3.3μF to 10μF bypass capacitor is needed if far from the main input filter capacitor, and the pin withstands reverse voltages up to ±10V. |
| 13 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 14 | IN | power_in | Supplies power to the device (pins 12 and 14 are both IN); a 3.3μF to 10μF bypass capacitor is needed if far from the main input filter capacitor, and the pin withstands reverse voltages up to ±10V. |
| 15 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 16 | NC | unconnected | No connect; may be floated, tied to IN or tied to GND. |
| 17 | EXPOSED PAD | power_in | Exposed pad is ground; must be soldered to the PCB ground and connected directly to pins 8 and 10 for best performance. |
