TABLE 1-1: ELECTRICAL CHARACTERISTICS
Electrical Characteristics: Limits in standard typeface are for T_J = 25°C and limits in boldface apply over the
junction temperature range of –40°C to +125°C. Unless otherwise specified, V_IN = V_OUT + 1V, I_L = 1 mA, C_L = 3.3 μF,
and V_ENABLE = V_DD. (Note 1).

Note 1: Specification for packaged product only.
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 100 mA. Changes in output voltage due to
heating 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 100 mA load pulse at V_IN =
26V for t = 10 ms.
