Q106 : BA00JC5WT (Variable Rated Voltage, 1.5A Secondary LDO Regulators)
Description
The BA□
□JC5 are low-saturation regulators with an output current of 1.5 A and a voltage accuracy of ±1%. A broad output
voltage range is offered, from 1.5V to 12V, and built-in overcurrent protection and thermal shutdown (TSD) circuits prevent
damage due to short-circuiting and overloading, respectively.

* For the BA00JC5WT, connect R1 and R2
externally between the ADJ and GND pins
and between the OUT and ADJ pins.
Equation: VOUT = Vc × (R1 + R2) / R1
(Vc = 1.25 V (Typ.))
The recommended R1 value is approximately
30 k
to 150 k
