Working Principles

The S-1142B35I-E6T1U is a low dropout (LDO) linear voltage regulator that works on the principle of controlling the voltage drop across its own internals to create a constant voltage regardless of the input voltage or load current. This is achieved by monitoring the output voltage through a control circuit and constantly adjusting the regulation of the pass transistor which keeps the output voltage constant. The control circuit allows for protection against over current, over voltage and overtemperature operation.

The S-1142B35I-E6T1U also has the added feature of being able to go into a low-power shutdown mode when the voltage drops below a certain level. This mode is useful to help extend battery life in applications where power consumption needs to be kept to a minimum. The S-1142B35I-E6T1U integrates a sophisticated control circuit which allows it to offer a very low dropout voltage and high output current to ensure stable and reliable operation in a wide range of conditions.
