µsec 10% V_R to 90% V_R, V_IN = 0V to V_R +1V,
R_L = 25Ω resistive.
1: V_R is the nominal regulator output voltage. For example: V_R = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V.
The input voltage V_IN = V_R + 1.0V, I_OUT = 40 mA.
2: TCV_OUT = (V_OUT-HIGH – V_OUT-LOW) *10⁶/(V_R * ∆Temperature), V_OUT-HIGH is equal to the highest voltage measured
over the temperature range, while V_OUT-LOW is equal to the lowest voltage measured over the temperature range.
3: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.
