SLVSGE2 March 2022 TPS629203
PRODUCTION DATA
The output voltage of the TPS629203 is adjustable. It can be programmed for output voltages from 0.6 V to 5.5 V, using a resistor divider from VOUT to GND. The voltage at the FB pin is regulated to 600 mV. The value of the output voltage is set by the selection of the resistor divider from Table 9-2. It is recommended to choose resistor values that allow a current of at least 2 μA, meaning the value of R2 should not exceed 300 kΩ. Lower resistor values are recommended for highest accuracy and most robust design.
