The company said the LDOs' input and output are stable, with 0.1 microfarads of input and output capacitance, and operate on a typical quiescent current of 50 microamperes. A shutdown function allows the output to be disabled, dropping the quiescent current to only 0.01 microamperes.
Designers must often drop the voltage from existing high-voltage rails, such as 12V and 24V rails, to power subsystem circuitry. The MCP1804 LDOs' 28V input and wide output voltage range provide designers with a means of doing this. Additionally, because the LDOs only require 0.1 microfarads of input and output capacitance, smaller and lower-cost ceramic capacitors can be used. The small and thermally capable package options make the LDOs ideal for space-constrained and high-power designs.
"We are pleased to expand our high-voltage LDO portfolio with the MCP1804 family," said Bryan J. Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "The flexibility of these 28V, 150 mA devices reinforces our goal of providing the complete product solutions that our customers have come to expect."
