Microchip MCP1804 Low Dropout Voltage Regulators

Microchip Technology introduced the MCP1804 Low Dropout Regulators (LDOs). The MCP1804 delivers up to 150 mA of output current and support output voltages from 1.8V to 18V. The MCP1804 LDOs are available in 3-pin SOT-89 and SOT-223 packages, as well as a 5-pin SOT-89 package, for $0.50 each in 10,000-unit quantities. They are also available in a 5-pin SOT-23 package for $0.48 each in 10,000-unit quantities. Samples are available now and volume production quantity orders can also be placed today.

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. The LDOs are available in a space-saving SOT-23, and thermally capable SOT-89 and SOT-223 packages. They are ideal for applications in the industrial and consumer markets, such as security systems, wireless communication systems, cordless phones and home appliances.

The MCP1804 LDOs’ 28V input and wide output voltage range provide designers with a flexible means of doing this. In addition, 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.
