VRH3101NTX from AnaSem, in a SOT-23-5. 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 | VIN | power_in | Positive supply input. Operating range 1.6V to 6.0V, absolute maximum -0.3V to +7.0V. A 1.0µF ceramic input capacitor (CIN) to VSS is recommended for stable input power. |
| 2 | VSS | power_in | Power ground / negative supply reference for the regulator. |
| 3 | EN | input | Chip enable / shutdown input. VENH ≥ 1.2V enables the regulator; VENL ≤ 0.3V puts it into shutdown mode (ISTB typ. 0.01µA) and triggers CL auto-discharge through internal ~160Ω resistance to VSS. EN high current 0.25-5.0µA; EN low current -0.1 to 0.1µA. |
| 4 | NC | unconnected | No connection (open). Leave floating on the PCB. |
| 5 | VOUT | power_out | Regulated voltage output, 3.10V ±1% for VRH3101 (VOUT × 0.99 to VOUT × 1.01 for the '1' accuracy grade in the 1.95-5.0V window). Maximum output current 250mA, over-current limit typ. 300mA, short-circuit current typ. 40mA. Requires a 1.0µF ceramic capacitor (CL) to VSS for phase compensation. Must not exceed VIN + 0.3V to avoid parasitic diode conduction. |
