LT3011EDD#PBF from Analog Devices, in a DFN-10-EP(3x3). 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 | Output supplies power to the load and requires a minimum 1μF output capacitor to prevent oscillations, with larger capacitors needed for large transient loads. |
| 2 | ADJ | input | Adjust pin is the error amplifier input, internally clamped to ±7V, with a 30nA bias current flowing into the pin, and sets the output range of 1.24V to 60V referenced to ground. |
| 3 | GND | power_in | Ground pin that must be connected directly to the exposed pad (pin 11) on the PC board for optimum electrical and thermal performance. |
| 4 | NC | unconnected | No internal connection; connecting this pin to a copper area provides a small improvement in thermal performance. |
| 5 | PWRGD | output | Open-collector power good flag indicates output is above 90% of nominal; no internal pull-up is present so an external pull-up resistor is required, and the maximum low-state pull-down current is 50μA. |
| 6 | CT | passive | Timing capacitor pin sets the delay between the output crossing the PWRGD threshold and PWRGD going high impedance, with 3μA charging current and a 1.67V PWRGD low-to-high voltage difference. |
| 7 | NC | unconnected | No internal connection; connecting this pin to a copper area provides a small improvement in thermal performance. |
| 8 | SHDN | input | Shutdown pin turns the output off when pulled low, may be driven by 5V logic or open-collector logic with a pull-up resistor, and must be tied to a logic high or VIN if unused. |
| 9 | NC | unconnected | No internal connection; connecting this pin to a copper area provides a small improvement in thermal performance. |
| 10 | IN | power_in | Input supply pin for the regulator, where a 1μF to 10μF bypass capacitor is sufficient if the device is more than six inches from the main input filter capacitor, and the device withstands reverse input voltages. |
| 11 | GND | power_in | Exposed pad is the ground connection and must be soldered to the PCB for electrical and thermal performance. |
