GENERAL DESCRIPTION
The SA57700 allows for a constant vibration force while operating
from a –0.3 V to 12.0 V input range and delivering up to 150 mA.
The Ground Current is only 80 µA typical independent of the load.
The output is turned off when input voltage drops below detection
voltage at 2.1 V. To minimize battery drain, (ON = low) SA57700
supply current drops to 0.1 µA max. Other features include thermal
shutdown protection, short circuit protection. The SA57700 is
available in a 5-pin SOT23 package.
FEATURES

TECHNICAL DESCRIPTION
ON pin
Drive ON high to provide power to the load. Drive ON low to disable
power to the load and reduce the supply current to maximum
Regulator stability and capacitor selection
Phase compensation is made for securing stable operation even if
the load current varies. For this reason, an output capacitor with
good frequency characteristics is needed. Set it as close to the
circuit as possible and make the wiring as short as possible. Use a
4.7 µF capacitor on the input and 4.7 µF capacitor on the output of
the SA57700. For a fast load transient response requires a larger
output capacitor value.
0.1 µA. Assume V is greater than VHDET 2.6 V, when ON goes

HIGH, output current rises to the current limit until V

regulation. While in regulation the output current drops to a lower
value sufficient to maintain motor speed. When ON goes LOW, the
regulator turns off, however, inertial energy in the motor exhibits a
slow output voltage decline. The SA57700 is designed to withstand
this condition with no negative effects. Connect ON terminal to V
when it is not used.
IN
Current Limit
The SA57700 includes a current limiter that monitors and controls
the pass transistor’s gate voltage, estimating the output current and
limiting it to about 270 mA. The output can be shorted to ground for
an infinite time period without damaging the part.
V
pin
IN
Input voltage drops below VLDET 2.1 V, which sets the output
voltage stop regulating while ON input is HIGH. The consumption
current flows even when output voltage is OFF due to input voltage
