VRD3333PTX

AnaSem · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-26

VRD3333PTX from AnaSem, in a SOT-26. 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 EN1 input 1-Channel enable input. Drive high (VENH ≥ 1.2 V, up to 6.0 V) to enable VOUT1; drive low (VENL ≤ 0.3 V, i.e. tie to VSS) to shut down channel 1. In shutdown the CL on VOUT1 is auto-discharged to VSS through RDIS (typ. 160 Ω).
2 VIN power_in Regulator input supply, 1.6 V to 6.0 V (absolute max −0.3 V to +7.0 V). Bypass to VSS with a ≥1 µF ceramic input capacitor placed close to the pin.
3 EN2 input 2-Channel enable input. Drive high (VENH ≥ 1.2 V, up to 6.0 V) to enable VOUT2; drive low (VENL ≤ 0.3 V) to shut down channel 2 and auto-discharge CL2 through RDIS (typ. 160 Ω).
4 VOUT2 power_out Channel-2 regulated output, factory-set to 3.30 V ±1% on VRD3333PTX. Supplies up to 250 mA with typ. 90 mV dropout at 100 mA. Requires a ≥1 µF ceramic output capacitor (CL2) to VSS for stability. Must not exceed VIN + 0.3 V (parasitic-diode constraint).
5 VSS power_in Common ground / power return for both regulators, reference, and enable logic.
6 VOUT1 power_out Channel-1 regulated output, factory-set to 3.30 V ±1% on VRD3333PTX. Supplies up to 250 mA with typ. 90 mV dropout at 100 mA. Requires a ≥1 µF ceramic output capacitor (CL1) to VSS for stability. Must not exceed VIN + 0.3 V.
