8/22

Note:

3

Dropout voltage is the input-to-output voltage difference at which the output voltage is

100mV below its nominal value. This specification does not apply for input voltages below

2.5V.

4

and the output voltage just reaching 95% of its nominal value

5

Typical thermal protection hysteresis is 20 °C

6

The minimum capacitor value is 1 µF, anyway the LD3985 is still stable if the compensation

capacitor has a 30 % tolerance in all temperature range.
