3 Description
The LMR16006Y-Q1 is a PWM DC-DC buck (step-
down) regulator. It is suitable for a wide range of
application from industrial to automotive for power
conditioning from an unregulated source. The
regulator’s standby current is 28 µA in ECO mode,
which is suitable for battery operating systems. An
ultra-low 1 µA shutdown current can further prolong
battery life. Operating frequency is fixed at 2.1 MHz
allowing the use of small external components while
still being able to have low output ripple voltage. Soft-
start and compensation circuits are implemented
internally, which allows the device to be used with
minimized external components. The LMR16006Y-Q1
is optimized for up to 600 mA load currents. It has a
0.765 V typical feedback voltage. The device has
built-in protection features such as pulse by pulse
current limit, thermal sensing and shutdown due to
excessive power dissipation. The LMR16006Y-Q1 is
available in a low profile SOT-6L package (2.9 mm x
1.6 mm).
