描述
The LTC1872 boasts a ±2.5% output voltage accuracy and consumes only 270μA of quiescent current. For applications where efficiency is a prime consideration, the LTC1872 is configured for Burst Mode operation, which enhances efficiency at low output current.
In shutdown, the device draws a mere 8μA. The high 550kHz constant operating frequency allows the use of a small external inductor.
The LTC1872 is available in a small footprint 6-lead SOT-23.
