Shenzhen JingYang · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
JY1105A-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 | Voltage input; the datasheet gives an operating input range of 1.7V to 6.0V and an absolute maximum of -0.3V to +7.0V, and recommends at least 1uF between Vin and ground. |
| 2 | VSS | power_in | Power ground for the regulator. |
| 3 | EN | input | Chip enable, active high: EN above 1.2V turns the output on, EN at or below 0.3V puts the device in standby (about 0.2uA maximum), and EN is internally pulled down by 4MΩ; absolute EN voltage range is -0.3V to +7.0V. |
| 4 | VOUT | input | No connection on fixed-output versions; on the adjustable version (JY1105A-ADJ) this pin is the feedback input at Vadj = 0.6V (±1.2%), with Vout = Vadj × (1 + R1/R2) set by external resistors, and the Adj voltage range is -0.3V to +7.0V. |
| 5 | VOUT | power_out | Regulated output, 0.8V to 5.0V for the adjustable version, rated for up to 500mA maximum output current with a 600mA typical current limit. |
