Micrel Semiconductor Offers the MIC3975 LDO Regulator

July 22, 2001 by Jeff Shepard

Micrel Semiconductor Inc. (San Jose, CA) is now offering a 750mA regulator for 2.5V to 1.8V or 1.65V conversion. The new MIC3975 LDO regulator was designed to power low-voltage microcontrollers, digital signal processors and programmable logic devices.

Features of the MIC3975 LDO include 300mV dropout voltage and full load, fixed- and adjustable-output voltages; logic-enable input; and an error flag to warn of output fault conditions. The device has reverse battery, current limit and thermal-shutdown protections. Micrel reports that it has a fast transient response and is stable with a ceramic output capacitor. The maximum input voltage is 16V and the temperature range extends from -40 to 125 degrees C.

"The MIC3975 operates with minimum headroom. It has a dropout voltage of only 300mV at its full load of 750mA," said Lisa Wong, LDO product-marketing engineer at Micrel.

The MIC3975 is offered in MSOP-8 packaging. When purchased in a quantity of 1,000, pricing starts at $1.40. Samples are available, and production quantities are stock to eight weeks ARO.
