Notes
1. The output voltage can be calculated using the following formula: VREG = Vref × k where k = R-----1---R--+---2--R-----2-- and
R1 + R2 ≤ 100 kΩ.
2. The regulator output will follow VP if VP < VREG + VREG(drop).
3. Limiting values as applicable for device types:
a) TDA3661T: VP ≤ 33 V and −40 °C ≤ Tamb ≤ +85 °C.
b) TDA3661AT: VP ≤ 45 V and −40 °C ≤ Tamb ≤ +125 °C.
