Linear Regulators (LDO) | CS8391

The CS8391 is a precision, dual 5V micropower linear voltage regulator. The switched primary output (V_OUT1) supplies up to 250mA while the secondary (V_OUT2) is capable of supplying 100mA. Both outputs have a maximum dropout voltage of 600mV and low reverse current. Quiescent current drain is typically 150?A when supplying 100?A from each output.

The ENABLE input provides logic level control of the primary output. With the primary output disabled, quiescent current drain is typically 100?A when supplying 100?A from the secondary output.

The CS8391 is extremely robust with protection provided for reverse battery, short circuit, and overtemperature on both outputs. The CS8391 is available in a 5-lead D²PAK.
