# VDD261SCTA

**AnaSem** · Voltage Reference · SOT-23

VDD261SCTA from AnaSem, in a SOT-23. 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 | output | CMOS push-pull detector output. Drives high (=VIN) when VIN is above the release voltage (VREL) and low (=VSS) when VIN falls below the detection voltage (VDET=2.6V). Sinks/sources up to ~9.5 mA typical at VIN=6.0V, VDS=2.1V. |
| 2 | VSS | power_in | Power ground / negative supply reference. Connect to system ground. |
| 3 | VIN | power_in | Positive supply and monitored voltage input. Operating range 0.7V to 6.0V (absolute max -0.3 to +7.0V). Typical supply current ~0.6 µA at VIN=1.5V. |

## CAD (KiCad official)

- Symbol: `VDD261SCTA`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `vdd261scta-etched.step` / `vdd261scta-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `vdd261scta.step` / `vdd261scta.glb` are the bare package body.
