SNOSC48O – JUNE 2000 – REVISED DECEMBER 2014

Feature Description (continued)

7.3.3 Short-Circuit Current Limit

The output current limiting circuitry of the LM2936 has been designed to limit the output current in cases where

the load impedance is unusually low. This includes situations where the output may be shorted directly to ground.

Continuous operation of the LM2936 at the current limit will typically result in the LM2936 transitioning into TSD

mode.

7.3.4 Shutdown (SD) Pin

The LM2936BM has a pin for shutting down the regulator output. Applying a Logic Level High (> 2 V) to the SD

pin will cause the output to turn off. Leaving the SD pin open, connecting it to Ground, or applying a Logic Level

Low (< 0.6 V) will allow the regulator output to turn on.

7.4 Device Functional Modes

The LM2936 design does not include any undervoltage lockout (UVLO), or overvoltage shutdown (OVSD)

voltage will be regulated; however, the device will be sensitive to any small perturbation of the input voltage.

Device dynamic performance is improved when the input voltage is at least 2 V greater than the output voltage.
