JY1107-1.2X

Shenzhen JingYang · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

JY1107-1.2X from Shenzhen JingYang, in a SOT-23. 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 GND/ADJ power_in Ground pin for the fixed-output versions and adjust pin for the adjustable version; the adjust pin current is typically 60 µA (max 120 µA) per the electrical characteristics.
2 VOUT power_out Regulated output pin, rated for output currents up to 700 mA, with fixed versions of 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.85 V, 3.0 V, 3.3 V and 5.0 V (1 % accuracy, 2 % for 1.2 V) and a stated output capacitor requirement of at least 22 µF for the adjustable version.
3 VIN power_in Regulator input pin with a recommended input voltage of 15 V maximum and an absolute maximum input voltage of 20 V, with a dropout of typically 1 V at 700 mA output current.
