The on-chip 150mA low dropout (LDO) linear regulator can be powered from the buck controller’s input supply, its own independent input supply or the buck regulator’s output. The buck controller incorporates an undervoltage lockout feature that shuts down the controller when the input voltage falls below 2.1V.The buck regulator provides a ±2.5% output voltage accuracy. It consumes only 210μA of quiescent current in normal operation with the LDO consuming an additional 50μA. In shutdown, a mere 10μA (combined) is consumed.For applications where efficiency is a prime consideration, the buck controller 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). High constant operating frequency of 550kHz allows the use of a small external inductor.The LDO is protected by both current limit and thermal shutdown circuits.The LTC3700 is available in a tiny 10-pin MSOP.
