ELECTRICAL CHARACTERISTICS(Cont.)

Notes: 1. The LR2126 output must be diode-clamped to ground. If used in a dual-supply system where the regulator

load is returned to a negative supply.

biased normally. If the voltage at the output terminal is forced to be higher than the voltage at the input terminal

this diode will get forward biased. This diode can withstand 1Amp of peak current and 200mA of DC current

typically.

3. Devices must be derated based on package thermal resistance at elevated temperatures.

4. Conditions for which the device is intended to be functional is indicated by operating ratings, but specific

performance limits isn’t be guaranteed. To make sure of specifications and test conditions, read Electrical

Characteristics. Only for the test conditions listed the guaranteed specifications can be applied. When the

device is not operated under the listed test conditions some performance characteristics may degrade.

5. Output voltage line regulation is the change in output voltage from the nominal value which is due to

change in the input line voltage. Which is defined as the change in output voltage from the nominal value

due to change in load current is output voltage load regulation. The load regulation and line regulation

specification include the typical number only. But, the limits for load and line regulation are included in the

output voltage tolerance specification.

6. At which the output drops 2% below the normal value dropout voltage is defined as the minimum input to

output differential voltage. Only to output voltages of 2.5V and above dropout voltage specification applies.

For output voltages below 2.5V, since the minimum input voltage is 2.5V, the drop-out voltage is nothing

but the input to output differential.
