■ The LTC®3700 is a constant frequency current mode stepdown (buck) DC/DC controller with excellent AC and DC
load and line regulation. 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. Dual Output Regulator in Tiny 10-Pin MSOP
