The LTC1772 boasts a 2.5% output voltage accuracy and consumes only 270A of quiescent current. For applications where efficiency is a prime consideration, the LTC1772 is configured for Burst Mode operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the external P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, the device draws a mere 8A. High constant operating frequency of 550kHz allows the use of a small external inductor. The LTC1772 is available in a small footprint 6-lead SOT-23.
