thereby preventing thermal overload. This thermal
management function is an effective means to prevent die
overheating since the load current is the principle heat
source in the IC.

ENABLE Function
and OFF. When the voltage on the ENABLE lead exceeds
1.4 V typ, the output pass transistor turns off, leaving a high
impedance facing the load. The IC will remain in Sleep
mode, drawing only 50 mA, until the voltage on this input
drops below the ENABLE threshold.
RESET Function
powers up until V
output voltage, or when V
is lower than 300 mV below the regulated output voltage. A
hysteresis of 50 mV is included in the function to minimize
oscillations.
ENABLE
The ENABLE function switches the output transistor ON
A RESET signal (low voltage) is generated as the IC
