Microchip Launches New Ultra-Low dropout (LDO) for Portable Devices and IoT


Nowadays, battery-consumed portable devices expected to run for a long time without recharging or replacing the battery. With this new product from Microchip, MCP1811, an ultra-low Iq of 250 nanoamps (nA) dropout (LDO), attempts to squeeze the last drop of the battery life.  It works by having a faster response time in accelerating wake-up speed and avoid an undervoltage situation where transient spike in voltage can lead to damage on sensitive devices.

The MCP1811 only needs 1 μF (2.2 μF for MCP1812) of output capacitance to ensure its stability while keeping a steady low output-voltage. It also comes with nine standard fixed output-voltage versions:  1V, 1.2V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V, and 4.0V. The 150/300 mA output current capability. It can be paired with other ultra-low current devices as well.

Lastly, the MCP1811 is a good choice for high-current demand ultra-long-life LDO applications where they need ultra-low power consumption during sleep mode. With its compact design, 1 x 1 millimeter (mm), it can meet the needs of a limited board space.
