Working Principles

The LM8335TLX/NOPB is a low dropout voltage regulator that maintains a stable output voltage even when the input voltage is close to the desired output voltage. It achieves this by utilizing a PNP pass transistor in series with the load, which drops the excess voltage across it.

When the enable pin (EN) is high, the regulator is turned on, and the output voltage (VOUT) is regulated to the desired value. When the EN pin is low, the regulator enters shutdown mode, reducing the current consumption to an ultra-low level.

The BYP pin is connected to a bypass capacitor, which helps improve stability and reduce noise in the output voltage.
