DESCRIPTION
The SS6730 is a low noise, low dropout linear
regulator, housed in a small SOT-23-5 o r
SOT-23-6W package. The device is in the “ON”
state when the SHDN pin is set to a logic-high
level. An internal P-MOSFET pass transistor is
used to achieve a low dropout voltage of 90mV at
50mA load current. It offers a high precision output
voltage of ±2%. The very low quiescent current
and low dropout voltage make this device ideal
for battery powered applications. The internal
reverse bias protection eliminates the
requirement for a reverse voltage protection
diode. The high ripple rejection and low noise
provide enhanced performance for critical
applications. An external capacitor can be
connected to the noise bypass pin to reduce the
output noise level.
