VRD1828MTX

AnaSem · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-6

VRD1828MTX from AnaSem, in a SOT-23-6. 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 Enable input for channel 1; driving it to VSS shuts down VOUT1 and discharges CL through the internal auto-discharge resistance (160 Ω typ.), with EN high level specified at 1.2 V to 6.0 V and EN low level at 0 to 0.3 V.
2 VIN power_in Common voltage input for both regulators, specified at 1.6 V to 6.0 V with an absolute maximum range of −0.3 V to +7.0 V, and a 1 µF input capacitor is recommended between VIN and VSS.
3 EN2 input Enable input for channel 2; driving it to VSS shuts down VOUT2 and discharges CL through the internal auto-discharge resistance (160 Ω typ.), with EN high level specified at 1.2 V to 6.0 V and EN low level at 0 to 0.3 V.
4 VOUT2 power_out Channel 2 regulated output, which must not exceed VIN + 0.3 V to avoid reverse current through the parasitic diode, and a at least 1.0 µF ceramic output capacitor should be connected close to this pin and VSS.
5 VSS power_in Power ground and common return for both regulators and the output capacitors.
6 VOUT1 power_out Channel 1 regulated output, which must not exceed VIN + 0.3 V to avoid reverse current through the parasitic diode, and a at least 1.0 µF ceramic output capacitor should be connected close to this pin and VSS.
