LDOs offer wide input and output voltage ranges.

Press Release Summary:




Featuring 28 V input, MCP1804 Low Dropout Regulators (LDOs) deliver up to 150 mA output current and support output voltages from 1.8-18 V. Input and output are stable, with 0.1 µF of capacitance, and operate on typ quiescent current of 50 µA. Shutdown function allows output to be disabled, dropping quiescent current to 0.01 µA. Available in SOT-23, SOT-89, and SOT-223 packages, LDOs support use of smaller ceramic capacitors and are suited for space-constrained and high-power designs.

LDOs with Wide Input and Output Voltage Ranges Unveiled by Microchip Technology



28V Input LDOs Deliver 150 mA Current; Support Output Voltages From 1.8 x 18V
CHANDLER, Ariz., Oct. 20 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the MCP1804 Low Dropout Regulators (LDOs), which deliver up to 150 mA of output current and support output voltages from 1.8 - 18V. 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, and are well-suited for applications in the industrial and consumer markets, such as security systems, wireless communication systems, cordless phones and home appliances.

Designers must often drop the voltage from exisiting 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 flexible 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."
