VDD251LCTA

AnaSem · Voltage Reference · SOT-23

VDD251LCTA 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. Driven to VIN (P-ch ON) when input is above the release voltage VREL, and pulled to VSS (N-ch ON) after the delay when input falls below VDET (2.5V nominal). Output rating: VSS-0.3 V to VIN+0.3 V; IOUT abs-max 50 mA.
2 VSS power_in Device ground / negative supply return. Reference for VIN, VDET, VREL, and VOUT low state.
3 VIN power_in Monitored input voltage and device supply. Operating range 0.7 V-6.0 V (abs-max -0.3 V to +7.0 V). Detector compares this rail against internal 2.5 V reference (±1%) with ~5% typ. hysteresis; typ. supply current 0.7 µA at VIN=2.0 V.
