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.  

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

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.
