VRD3033PTX

AnaSem · Linear Voltage Regulators (LDO) · SOT-26

VRD3033PTX from AnaSem, in a SOT-26. 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 EN1 input Channel 1 enable input, with VENH of 1.2V to 6.0V turning the channel on and VENL of 0.3V max shutting it down (CL auto-discharge active).
2 VIN power_in Voltage input for both regulators, operating range 1.6V to 6.0V (absolute maximum 7.0V), with a 1.0µF input capacitor to VSS recommended.
3 EN2 input Channel 2 enable input, with VENH of 1.2V to 6.0V turning the channel on and VENL of 0.3V max shutting it down (CL auto-discharge active).
4 VOUT2 power_out Channel 2 regulated output, up to 250mA with 300mA limit current, requiring at least a 1.0µF ceramic output capacitor to VSS.
5 VSS power_in Power ground for both regulator channels.
6 VOUT1 power_out Channel 1 regulated output, up to 250mA with 300mA limit current, requiring at least a 1.0µF ceramic output capacitor to VSS.
