VRH1402LTX

AnaSem · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

VRH1402LTX from AnaSem, in a SOT-25. 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; the absolute maximum input voltage range is -0.3 V to +7.0 V and the stated operating voltage range is 1.6 V to 6.0 V.
2 VSS power_in Power ground; pulling EN to VSS activates the internal switch that discharges the output capacitor so VOUT quickly returns to the VSS level.
3 EN input Chip enable; the datasheet gives no separate EN voltage limit, and driving EN to VSS triggers the internal auto-discharge switch.
4 NC unconnected Non-connection pin, left open (no internal connection).
5 VOUT power_out Regulated output at 0.9 V to 5.0 V in 0.05 V steps, with 250 mA maximum output current and 300 mA current limit; absolute maximum output range is VSS - 0.3 V to VIN + 0.3 V.
