The TS31x23 high voltage linear regulator consists of a low
power amplifier with a high voltage p-channel pass gate.
The linear regulator has a wide operating range, and is ideal
for systems that may have large voltage transients and require
the output load to remain regulated.
An analog current limit is used to limit output current and
protect the regulator from external short circuits.

Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute–maximum–rated conditions for extended periods may affect device reliability.
Note 2: All voltage values are with respect to network ground terminal.
