JY1105-H330BX from Shenzhen JingYang, in a SOT-23-5L. 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 | Input supply pin for the regulator, specified from 1.7 V to 6.0 V operating, with an absolute maximum of -0.3 V to +7.0 V, and at least 1 µF should be placed between VIN and GND. |
| 2 | VSS | power_in | Power ground pin, which is the reference for the output voltage limits (Vout range Vss-0.3 V to Vin+0.3 V) and the EN thresholds. |
| 3 | EN | input | Active-high chip enable: a level of at least 1.2 V (6 V maximum) turns the regulator on, a level of 0.3 V or less turns it off, and the pin is pulled down internally by 4 MΩ so an open pin disables the output. |
| 4 | NC/ADJ | unconnected | No internal connection on the fixed-output JY1105NF (this MPN is a fixed 3.3 V part); on the adjustable JY1105AF it is the Adj feedback input, trimmed to a 0.6 V reference, used with R1 and R2 to set Vout. |
| 5 | VOUT | power_out | Regulated output rated for 500 mA maximum, with an output capacitor of at least 1 µF to ground (3.3 µF if Vout is below 1.2 V), placed as close to the pin as possible. |
