LT3021EDH#PBF

Analog Devices · Linear Voltage Regulators (LDO) · DFN-16(5x5)

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.
