ISL21090BFB850Z-TK

RENESAS · Voltage References · SOIC-8

ISL21090BFB850Z-TK from RENESAS, in a SOIC-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 DNC unconnected Do Not Connect pin; the absolute maximum ratings state that no connections are permitted to DNC pins.
2 VIN power_in Input voltage connection; the 5.0V option specifies a VIN range of 7V to 36V, with VIN to GND rated -0.5V to +40V.
3 COMP passive Compensation and noise reduction capacitor; a 0.01µF capacitor must be added to COMP for stabilization on the 1.25V option.
4 GND power_in Ground connection for the device, referenced by all voltage ratings given to GND.
5 TRIM input Voltage reference trim input, which is the negative feedback divider point of the output op amp and is used to adjust VOUT above or below the factory value.
6 VOUT power_out Voltage reference output; the 5.0V option delivers 5.0V with sourcing up to 20mA, and VOUT to GND (10s) is rated -0.5V to VOUT + 0.5V.
7 DNC unconnected Do Not Connect pin; the absolute maximum ratings state that no connections are permitted to DNC pins.
8 DNC unconnected Do Not Connect pin; the absolute maximum ratings state that no connections are permitted to DNC pins.
