JSMSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
JSM2019-ADJYN5G from JSMSEMI, in a SOT-23-5. 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 of supply voltage, 1.2V to 5.5V recommended operating range (-0.3V to 6.5V absolute maximum to GND). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input; pulling it low shuts the regulator down (10nA typical shutdown current), -0.3V to 6V absolute maximum. |
| 4 | SNS | input | Sense of output voltage; tied to VOUT for fixed output or to the R1/R2 divider midpoint for adjustable output, -0.3V to 6V absolute maximum. |
| 5 | VOUT | power_out | Output of the regulator, up to 300mA output current, stable with a ceramic output capacitor (1uF shown in application circuits). |
