LR8106B-TJ

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LR8106B-TJ from LR, 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 Input voltage pin, with a maximum input supply voltage of 6.5 V.
2 GND power_in Ground pin; the datasheet gives no separate electrical limit for this pin.
3 EN input Enable pin with an enable high level of 0.7 V and an enable low level of 0.2 V.
4 FB input Feedback pin; feedback voltage is 0.73 V typical (0.715 V min, 0.745 V max).
5 VOUT power_out Regulated output pin; maximum output current is 500 mA, and the datasheet gives no other limit for this pin.
