Note 1: Temperature coefficient is measured by the “box” method, i.e., the maximum ∆V
OUT
/ V
OUT
is divided by the maximum ∆T.
Note 2: Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from T
MAX
to T
MIN
.
Note 3: Dropout voltage is defined as the minimum differential voltage (V
IN
- V
OUT
) at which V
OUT
decreases by 0.1% from its
original value at V
IN
= 5.0V (V
IN
= 5.5V for V
