1. Select these diodes as specified in "5V Regulator" section on page 4.
2. This operational amplifier should be use for applications intend for ambient temperature range of 0°C to
+70°C.
For ambient temperature range of -25°C to +85°C replace it with KA258ADTF_NL.
For ambient temperature range of -40°C to +85°C replace it with TI's TLV342AID.
