LDO Extends Battery Life

Microchip Technology’s MCP1811 linear Low Dropout (LDO) regulator promises to extend battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs. With an Iq of 250 nA versus the approximately 1-µA operational of traditional devices, the MCP1811 LDO reduces quiescent current to save battery life.

 

Ideal for IoT and battery-operated applications such as wearables, remotes and hearing aids, the 250 nA ultra-low Iq minimizes standby or shutdown current. Reducing standby power consumption is critical in remote, battery-powered sensor nodes, where battery replacement is difficult and operating life requirements are high. Available in package options as small as 1 mm x 1 mm, the MCP1811 consumes minimal board space.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.

 

Additionally, the MCP1811 offers a faster load line and transient response when compared to other ultra-low Iq LDOs. Faster response times can accelerate wake-up speed in devices such as monitors or sensors that require immediate attention. Faster transient response can help designers avoid under-voltage and overvoltage lockout measures used in sensitive applications where transient spikes can lead to catastrophic results.

 

The MCP1811 is available now with pricing starting at $0.28 each/10,000 in a 1 x 1 mm DFN package. For greater insights, checkout the MPC1811 datasheet.
