CMOS LDO voltage regulators for Microchip with 150 mA of output current

Microchip has announced the MCP1804, a family of CMOS low dropout (LDO) voltage regulators that deliver up to 150 mA of output current and operates with a typical quiescent current of 50 microamperes. The MCP1804 is suitable for industrial and consumer applications such as security systems, wireless communication systems, cordless phones and home appliances.

The key features of the MCP1804 LDOs are,

Input operating voltage ranges from 2.0V to 28.0V
0.01 µA of typical shutdown current
Standard output voltage options (1.8V, 2.5V, 3.0V, 3.3V, 5.0V, 10.0V, 12.0V)
Output voltages ranges from 1.8V to 18.0V in 0.1V increments
±2% of output voltage accuracy
Stable with ceramic output capacitors down to 0.1 µF
LDO voltage, 260 mV typical at 20 mA, VR = 3.3V
Current limit protection with current foldback
High PSRR: 50 dB typical at 1 kHz

The MCP1804 LDOs only require 0.1 microfarads of input and output capacitance, small and low-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."
