The CA3277 dual 5V regulator was designed to perform
reliably in harsh Automotive and Industrial environments
where reverse voltages and unclamped inductive loads are
commonly present. The primary 5V regulator OUT1 is
generally used to power a microprocessor and backup
CMOS memory. For systems requiring low power operation,
the auxiliary 5V regulator, OUT2 can be disabled by applying
a logic low signal to the ENABLE pin. Both regulators are
capable of supplying up to 100mA at 5V and are internally
protected against over-voltage, over-current and over-temperature
conditions. This Application Note explores the basic
structure of the CA3277 and presents several examples on
applying the unique features of this device.
