VRH1502LTX

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

VRH1502LTX 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 voltage range 1.6V to 6.0V (absolute maximum -0.3V to +7.0V).
2 VSS power_in Power ground.
3 EN input Chip enable pin for the On/Off circuit; EN=VSS turns the regulator off and discharges the output capacitor through the internal switch.
4 NC unconnected No connection (open).
5 VOUT power_out Regulated output, 250mA maximum output current with 300mA current limit, stable with a 1.0µF ceramic capacitor.
