LT3021ES8-1.8#PBF

Analog Devices · Pre-ordered Chips · SO-8

LT3021ES8-1.8#PBF from Analog Devices, in a SO-8. 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; the pin may be left floating, tied to IN, or tied to GND.
2 OUT power_out Supplies power to the load; a minimum output capacitor of 3.3μF (ESR of 0.2Ω or less) is required to prevent oscillations.
3 SENSE input Sense point for the internal resistor divider on the fixed-voltage device, which should be tied directly to the OUT pin for best results.
4 AGND power_in Ground reference for the device.
5 SHDN input Pulling SHDN low turns the output off; it can be driven by logic or an open collector/drain with a pull-up resistor, and must be connected to VIN if unused since the device does not function when SHDN is unconnected.
6 PGND power_in Ground pin for the power path of the regulator.
7 NC unconnected No connect; the pin may be left floating, tied to IN, or tied to GND.
8 IN power_in Supplies power to the device with a 3.3μF to 10μF bypass capacitor recommended if it is more than six inches from the main input filter capacitor; input voltage range is 0.9V to 10V with ±10V absolute maximum.
