Zetex regulator provides 3.3V output voltage

Zetex Semiconductors rolled out a new voltage regulator that meets the needs of circuits subjected to a wide variation in supply voltage.

Supporting an input voltage range from 5V to 24V, the ZMR330 produces a high stability 3.3V output voltage and an output current up to 50mA. Provided in the SOT23 package, this miniature 3-pinned regulator can offer local regulation where board space is at a real premium, and with a typical quiescent current rating of 120?A, the part provides useful power economy when idle, said the company.

The operating temperature range of the regulator is from -55°C to 125°C, and its internal current limit and thermal overload functions ensure its protection from extreme operating conditions. According to the pres release, the addition of a series input resistor enables the ZMR330 to withstand automotive voltage transients.
