UTC UR0033 LINEAR INTEGRATED CIRCUIT

Over- current Protection Circuit

The over-current protection circuits are built in at the outputs. They protect the IC from being damaged when the

load is short-circuited or subjected to an over current condition. This protection circuits perform holdback current

limiting.

Thermal Protection Circuit

A thermal shut down circuit (T.S.D.) is built into the IC to prevent damage due to overheating, Therefore, all the

outputs are turned off when the T.S.D. circuit is activated and are turned on when the temperature recedes to the

specified level. However, the T.S.D. circuit is only for extreme conditions and the regulator circuit should still be

designed for the IC not to exceed TJ(max)=150℃.

Grounding

It is recommended that every capacitor (bypass and output capacitors) is grounded to PIN3 using single-point

connections.

Electromagnetic Fields

The IC is susceptible to strong electromagnetic fields and may cause malfunction. Therefore, caution should be

used when placing it on the PCB.

Protection Diodes

It is recommended that protection diodes be used when the output is connected to an inductive load.
