LTC1502-3.3

Short-Circuit Protection

When the output is shorted to ground, the LTC1502-3.3

will continuously charge the C2 capacitor up to approxi-

bring the C2 voltage below the COMP2 start-up compara-

tor trip voltage, the output charge pump will be forced

Hi-Z while C2 charges up again. Hence, the internal charge

resulting output short-circuit current is limited to under

20mA (typ) thereby allowing the LTC1502-3.3 to endure

an indefinite output short circuit without damage. When

the short is removed, the part will start up, and operate

normally.
