Shenzhen JingYang · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
JY1103-H300BX 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 | Voltage input, operating range 1.6V to 6.0V. |
| 2 | GND | power_in | Power ground (VSS). |
| 3 | EN | input | Chip enable; pulling EN to VSS turns the output off and discharges the output capacitor through an internal switch. |
| 4 | NC | unconnected | Pin 4 has no entry in the SOT23-5L column of the pin table, so its function is not stated; it is drawn on the package outline. |
| 5 | VOUT | power_out | Regulated output, 3.0V for this part number, with maximum output current of 300mA and a 300mA over-current limit. |
