JSM2019-ADJYN5G

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).
