Electrical Characteristics
T
1. The AAT1232 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured
2. Switching input current will vary with R1, R2, R3 resistor values.
3. Some improvement in line and load regulation is possible with smaller resistor values.
