The MC34160 Series is a voltage regulator and supervisory circuit containing
many of the necessary monitoring functions required in microproces sor based
systems. It is specifically designed for appliance and industrial applications,
offering the designer a cost effective solution with minimal external components.
These integrated circuits feature a 5.0 V/100 mA regulator with short circuit
current limiting, pinned out 2.6 V bandgap reference, low voltage reset
comparator, power warning comparator with programmable hysteresis, and an
uncommitted comparator ideally suited for microprocessor line synchronization.

Additional features include a chip disable input for low standby current,
and internal thermal shutdown for over temperature protection.

These devices are contained in a 16 pin dual–in–line heat tab plastic
package for improved thermal conduction.
