LTC3405A-1.375 - 1.375V, 1.5MHz, 300mA Synchronous Step-Down Regulators in ThinSOT

Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.

The LTC3405A-1.375 is specifically designed to work well with ceramic output capacitors, achieving very low output voltage ripple and a small PCB footprint.

The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. The LTC3405A-1.375 is available in a low profile (1mm) ThinSOT package.

For other output voltages, refer to the LTC3405A and LTC3405A-1.5/LTC3405A-1.8 data sheets.
