sorry don't know the SOT package numbers, did look but not found



Perhaps voltage regulator or bucky controllers BJSQ



5 pin , size of body area, 2.8 x 1.5mm

same physical type but top code JAPL


JB



1G (number one not I)
4 pin on perhaps a pass transistor, size of body 4.3x 2.4mm

The BJSQ is ohmic and heating up loading down the 9V battery. 4 actual pins

0V, 9V, an output that should be about 1.5V less than an external reference voltage of 5V applied to the fourth pin. If no info found I will try an LM317 and a couple of resistors to set at 3.5V .
