Product details

The Analog Devices LTC1701BES5#TRMPBF is a current-mode step-down (buck) regulator that delivers up to 500 mA from an input rail of 2.5 V to 5.5 V. Output is adjustable from 1.25 V up to 5 V.

The 500 mA rating is the maximum continuous output current. The 1 MHz switching rate keeps inductor ripple current manageable.

ROHS3 compliance is confirmed for the TSOT-23-5 package.

TSOT-23-5 footprint and tape options

The part is supplied in a TSOT-23-5 package (SOT-23-5 Thin variant). No external compensation network is required.

Frequently asked questions

Can LTC1701BES5#TRMPBF be used in a 3.3V to 1.8V conversion?

Yes. The input range covers 3.3 V, and the adjustable output can be set to 1.8 V (minimum 1.25 V) with two external resistors. The 500 mA output is enough for many MCU and FPGA core rails.
