Zetex Semiconductors Presents ZMR330 Voltage Regulator

Zetex Semiconductors (UK), a subsidiary of Zetex plc (Chadderton, Oldham), announced its ZMR330 voltage regulator, which supports an input-voltage range from 5 V to 24 V, to produce a high-stability 3.3 V output voltage and an output current up to 50 mA.

Provided in the SOT23 package, this miniature three-pinned regulator can offer local regulation where board space is at a real premium. With a typical quiescent current rating of just 120 µA, the part provides useful power economy when idle. 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. The addition of a series input resistor enables the ZMR330 to withstand automotive voltage transients.
