CS8182YDFR8G from onsemi, 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 | VOUT | power_out | Regulated output. Sources up to 200 mA and tracks the VREF input (VOUT = VREF when Adj is tied to VOUT). Requires a ≥10 µF output capacitor for loop stability (ESR 0.1-1.0 Ω @ 10 kHz). |
| 2 | GND | power_in | Ground return. Pins 2, 3, 6, 7 in the SO-8 package are all internally bonded to the ground / thermal lead frame (internally fused leads) and should all be tied to the PCB ground plane for thermal dissipation. |
| 3 | GND | power_in | Ground return. Internally fused with pins 2, 6, and 7 to serve as the SO-8 thermal path. Tie to the PCB ground/heatsink copper. |
| 4 | Adj | input | Adjust lead - inverting input of the internal tracking op-amp. Tie directly to VOUT for VOUT = VREF, or drive from a resistor divider between VOUT and GND (or between VOUT and an external reference) to set VOUT above or below VREF. Draws only ~0.2 µA typ (1.0 µA max) bias current in regulation. |
| 5 | VREF/ENABLE | input | Reference voltage and enable input - non-inverting input of the internal tracking op-amp. Applying a valid reference (>2.75 V typ) enables the regulator and sets the target VOUT. Pulling this pin below 0.80 V (typ 2.00 V threshold) puts the device into sleep mode drawing ~30 µA (55 µA max). Input bias 0.2 µA typ, 1.0 µA max. |
| 6 | GND | power_in | Ground return. Internally fused with pins 2, 3, and 7 to form the SO-8 thermal path. Tie to the PCB ground/heatsink copper. |
| 7 | GND | power_in | Ground return. Internally fused with pins 2, 3, and 6 to form the SO-8 thermal path. Tie to the PCB ground/heatsink copper. |
| 8 | VIN | power_in | Unregulated input supply. Recommended continuous operating range 3.4 V to 45 V (absolute maximum −16 V to +45 V, tolerant of 45 V load-dump and −50 V reverse polarity transients). A 1.0 µF bypass capacitor (C1) is recommended if the regulator is remote from the power source filter. |
