The linear regulator maintains its output voltage to within ±5% as long as the linear regula-
tor is dissipating less than 0.75 W. Thermal shutdown turns the regulator off when it over-
heats. Figure E-1 shows the power operating curves for the specified VIN range of 3–30 V
DC. Note that while a VIN range of 3–30 V is possible, 3–15 V is recommended to allow
reasonable current.
The LP3500 can operate at various different power levels, depending on which sections of
the board are turned off using the

NOTE: RxE always remains active to allow the LP3500 to “listen” while it is in the
power-save mode.
