Linear Technology LTC3388EDD-1#TRPBF High Efficiency Nanopower Step-Down Regulator

The LTC3388EDD-1#TRPBF is a cutting-edge, high-efficiency, nanopower step-down regulator from Linear Technology, an Analog Devices brand. This regulator is meticulously engineered to provide a consistent and reliable low-power supply solution for battery-powered and energy-harvesting applications, where power efficiency and extended battery life are of paramount importance.

Operating from an input voltage range of 2.7V to 20V, the LTC3388EDD-1#TRPBF is capable of delivering an adjustable output voltage from 1.8V to 5V, with an output current up to 20mA. The device features an ultralow quiescent current of only 720nA, which significantly reduces the power drain on batteries, thereby extending the operational lifespan of the application it powers.

The LTC3388EDD-1#TRPBF employs a unique Burst Mode® operation that enhances its efficiency at light loads, making it an ideal choice for remote, low-power applications such as wireless sensors, energy harvesting, and standby power systems. Its internal synchronous rectification further improves efficiency, and the no-load quiescent current is minimized to conserve power when the load is disconnected.

Designed with the user in mind, this step-down regulator comes in a compact 8-lead DFN package with a 3mm x 3mm footprint, which is perfect for space-constrained applications. The LTC3388EDD-1#TRPBF also includes over-temperature and over-current protection, ensuring the safety and reliability of the device under various operating conditions.

Key features of the LTC3388EDD-1#TRPBF include:

• High efficiency: capable of up to 95% efficiency
