VRH1902LTX

AnaSem · Linear Voltage Regulators (LDO) · SOT-23-5

VRH1902LTX from AnaSem, in a SOT-23-5. 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 VIN power_in Voltage input, operating range 1.6V to 6.0V with an absolute maximum of -0.3V to +7.0V.
2 VSS power_in Power ground, reference for the output voltage range limit of VSS-0.3V.
3 EN input Chip enable input for the On/Off circuit; EN=VSS turns the output off and discharges CL through the internal switch.
4 NC unconnected Non connection (open), not internally connected.
5 VOUT power_out Regulated output, up to 250mA maximum output current with 300mA over-current limit and a 1.0µF ceramic output capacitor.
