The LTC3388EDD-1#TRPBF is a 20V high efficiency nanopower step-down regulator manufactured by Analog Devices. It is designed for applications requiring efficient power conversion with minimal power consumption.
The device features a wide input voltage range from 2.7V to 20V. Its quiescent current is very low, measuring 400nA when enabled under UVLO conditions and ranging up to 3000nA when not sleeping. The output voltage is regulated and can be selected for various levels, with specific sleep and wake-up thresholds defined for each output voltage.
Key electrical characteristics include a PGOOD threshold between 83% and 92% of the selected VOUT, and an available output current of 50 mA. The PMOS switch has an on-resistance of 1.1 Ω, and the NMOS switch has an on-resistance of 1.3 Ω. The maximum duty cycle is 100%.
This regulator is suitable for various power management applications where efficiency and low power draw are critical. It is typically available in a surface mount package.
