Microchip’s LDOs Enable Smaller, More Efficient Designs

\[September 12, 2006\] For low-voltage, high-current applications in space-constricted products, the MCP1827 and MCP1827S low dropout regulators (LDOs) are available in small, thermally efficient 3- and 5-pin packages, and support output currents up to 1.5A. Input voltages range from 2.3V to 6.0V and outputs range from 0.8V to 5V while specifying a full-current dropout voltage of 330 mV typical. The devices feature a quiescent current of 120 µA during regulation and are ceramic-output-capacitor stable. The 5-pin MCP1827 includes power-good plus shutdown functions and is available in fixed or adjustable output-voltage versions. The 3-pin MCP1827S is a cost-effective alternative for applications not requiring power-good and shutdown. Prices for the MCP1827 in 5-pin and MCP1827S in 3-pin DDPAK and TO-220 packages range from $1 to $1.17 each/10,000. MICROCHIP TECHNOLOGY INC., Chandler, AZ. (888) 628-6247.
