DESCRIPTION
AIC1733 is a 500mA low noise, low dropout
linear regulator, and is housed in small SOT-23-5
package. The device is in the “ON” state when
the SHDN pin is set to logic high level. An
internal P-MOSFET pass transistor is used to
achieve 650mV low dropout voltage at 500mA
load current. It offers high precision output
voltage of ±2%. The quality of low quiescent
current and low dropout voltage makes this
device ideal for battery power applications. The
internal reverse bias protection eliminates the
requirement for a reverse voltage protection
diode. The high ripple rejection and low noise of
AIC1733 provide enhanced performance for
critical applications. The noise bypass pin can be
connected an external capacitor to reduce the
output noise level.
