G
Description
The GSC2146 series of positive, linear regulators feature low quiescent current (30 A typ.) with low dropout
voltage, making them ideal for battery applications. The space-saving SOP-8 package is attractive for “Pocket”
and “Hand Held” applications.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under
the “Worst” of operating conditions.
In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and ground.
The GSC2146 is stable with an output capacitance of 2.2 F or greater.

... Full current is restored when the voltage exceeds 0.8 volts. External Capacitors The GSC2146 is stable with an output capacitance to ground of 2 greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response ...
