SGM620XS8G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

SGM620XS8G from SGMICRO, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RG passive Gain setting pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000.
2 IN- input Inverting input pin of the instrumentation amplifier. Input impedance 10GΩ
3 IN+ input Non-inverting input pin of the instrumentation amplifier. Input impedance 10GΩ
4 -VS power_in Negative power supply pin. Operating range -2.3V to -18V for dual supply, or GND for single-supply operation up to 36V total across +VS to -VS.
5 REF input Voltage reference pin used to shift the output level. Must be driven from a low-impedance source (reference input resistance ~18kΩ, reference input current ~30µA typ).
6 OUT output Rail-to-rail output pin. Drives load (RL = 2kΩ nominal). Short-circuit current typically 24mA. Output swing within ~310mV/150mV of the supply rails at ±18V.
7 +VS power_in Positive power supply pin. Operating range +2.3V to +18V for dual supply, or 4.6V to 36V for single-supply operation.
8 RG passive Gain setting pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000.
