ZXTR2105FQ-7

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

ZXTR2105FQ-7 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Power ground reference. Tie to system ground. Return for both the zener bias current and the load current.
2 VOUT power_out Regulated 5V output (4.75V-5.25V) at up to ~15mA nominal load. When VIN < 7V, VOUT clamps to VIN − 1V. Absolute-max on this pin is the smaller of VIN+5V or +10V w.r.t. GND. Recommend a 10µF cap to GND and a minimum ~10µA load to maintain regulation.
3 VIN power_in Input supply, −0.3V to +60V absolute max. Regulated output requires 7V ≤ VIN ≤ 60V. Recommend a 1µF decoupling capacitor to GND. Continuous input current 320mA max; peak pulsed 2A.
