DEFINITIONS

General

All measurements are performed using short pulse low

duty cycle techniques to maintain junction temperature as

close as possible to ambient temperature.

Input to Output Differential Voltage

The Input to Output Differential Voltage parameter is

defined for specific output current values and specified over

Temperature range.

Quiescent and Disable Currents

current (measured through the LDO input pin) and the

output load current. If Enable pin is set to LOW the regulator

reduces its internal bias and shuts off the output, this term is

Current Limit

Current Limit is value of output current by which output

voltage drops below 90% of its nominal value.

Thermal Protection

Internal thermal shutdown circuitry is provided to protect

the integrated circuit in the event that the maximum junction

temperature is exceeded. When activated at typically 175

°C,

the regulator turns off. This feature is provided to prevent

failures from accidental overheating.

Maximum Package Power Dissipation

The power dissipation level is maximum allowed power

dissipation for particular package or power dissipation at

which the junction temperature reaches its maximum

operating value, whichever is lower.
