Zetex Regulator Manages Supply Voltage Swings

NewsSouth-East European INDUSTRIAL Мarket - issue 1/2005

Meeting the needs of circuits subject to a wide variation in supply voltage, the ZMR330 voltage regulator from Zetex Semiconductors supports an input voltage range from 5V to 24V, to produce 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 just 120µA, the part provides useful power economy when idle. The addition of a series input resistor enables the ZMR330 to withstand automotive voltage transients.
