DESCRIPTION

The SG29085/85A is a dual 8.2V/5V positive voltage regulator. One output is a high current (up to 1000 mA) regulator that can be turned on or off by a high impedance low current TTL compatible switch. The second or standby output remains on regardless. The on/off switch not only shuts off the high current output but actually puts the IC in a micropower mode making possible a low quiescent current. This unique characteristic coupled with an extremely low dropout, (.55V for output current of 10mA) makes the SG29085/85A well suited for power systems that require standby memory. The SG29085/85A includes other features which were originally designed for automotive applications.
