Note 1: Specification for packaged product only. Devices are ESD sensitive. Handling precautions recommended.

2: Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total

temperature range.

3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are

tested for load regulation in the load range from 0.1 mA to 200 mA. Changes in output voltage due to heat-

ing effects are covered by the thermal regulation specification.

4: Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its

nominal value measured at 1V differential.

5: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current

drawn from the supply is the sum of the load current plus the ground pin current.

6: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipa-

tion is applied, excluding load or line regulation effects. Specifications are for a 200 mA load pulse at VIN =

26V for fixed and VIN = 16V for adjustable at t = 10 ms.
