DC and AC characteristics

This section summarizes the DC and AC characteristics of the device. The parameters in

the DC and AC characteristics table that follows are derived from tests performed under the

test conditions (see Table6 on page9). Designers should check that the operating

conditions in their circuit match the operating conditions when relying on the quoted

parameters.

≤ IL ≤ 16µA(4)(5)

With negative current flowing into STLM20 and positive current flowing out, can typically sink less than 1µA

and source is 16µA.

RegL

Load regulation(6)

Measured at constant junction temperature, with pulse testing and low duty cycle. Output changes due to

heating may be calculated by multiplying internal dissipation by thermal resistance.
