JY1105-ADJBX
Shenzhen JingYang · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
JY1105-ADJBX 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; the datasheet gives an operating input range of 1.7V to 6.0V and an absolute maximum of -0.3V to +7.0V, with at least 1µF recommended between Vin and ground. |
| 2 | VSS | power_in | Power ground pin, which is the ground reference for the regulator and must be connected to the system ground. |
| 3 | EN | input | Active-high chip enable; the EN high level is 1.2V to 6V and the low level is at most 0.3V, and the pin is pulled down internally by 4MΩ so that the part is off when EN is open or low. |
| 4 | NC/ADJ | passive | Adjustable-version feedback input (JY1105AF/ADJ) where Vout = Vadj × (1 + R1/R2) with Vadj trimmed to 0.6V (0.593V to 0.607V), and the Adj input bias current is limited to ±0.1µA. |
| 5 | OUT | power_out | Regulated output pin, which is adjustable from 0.8V to 5.0V in the adjustable version and must have at least 1µF (3.3µF when Vout is below 1.2V) to ground for stability. |
