VRH2851NTX 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 | Regulator input supply. Operating range 1.6 V to 6.0 V, absolute max -0.3 V to +7.0 V. A 1.0 µF ceramic input capacitor CIN is recommended between VIN and VSS for stable input power. |
| 2 | VSS | power_in | Power ground / negative supply reference for the regulator. |
| 3 | EN | input | Chip enable / shutdown input. VENH ≥ 1.2 V (max 6.0 V) turns the regulator on; VENL ≤ 0.3 V shuts it down, dropping to typ. 0.01 µA standby current and engaging CL auto-discharge via RDIS ≈ 160 Ω. Do not leave floating. |
| 4 | NC | unconnected | No connection (open). Leave floating or tie to VSS; do not use as a route-through. |
| 5 | VOUT | power_out | Regulated 2.85 V output (±1%). Drives up to 250 mA continuous (300 mA current limit). Requires a ≥1.0 µF ceramic output capacitor CL to VSS for phase compensation. Must not exceed VIN+0.3 V (parasitic diode to VIN). |
