Linear Low Dropout (LDO) Regulators

Power management is crucial in a world that runs on battery power. The ability to drastically lower power consumption during standby or sleep modes is no longer a luxury and Microchip offers a wide variety of linear dropout regulators to manage power consumption. This is especially true in mobile medical applications that have extended use between charging cycles. Consumers are also looking to squeeze every bit of battery power they can from each charge cycle, and that demand requires efficient low dropout regulators to optimize standby power usage.

Microchip has a large selection of LDO regulators with the highest performance for quiescent current. They now offer the lowest quiescent current LDO in the market, consuming only 20 nA (typical) while operating with no load condition. By reducing the quiescent current, customers' applications can stay in standby/sleep mode up to 20 times longer than leading low quiescent current LDOs in the market. These LDOs are in small packages from 1 mm x 1 mm DFN to SOT-23 packages with capacitor-less operation to minimize the footprint and reduce the PCB usage for congested real estate. The wide selection of packages, input voltage ranges, and other key attributes make these LDOs ideal for battery-powered applications, such as wearables, key fobs, GPS, handheld equipment; hearing aids, Bluetooth® earphones, and more.
