DC and AC characteristics
STLM20
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 Table 6 on page 10). Designers should check that the operating
conditions in their circuit match the operating conditions when relying on the quoted
parameters.

1. Valid for Ambient Operating Temperature: TA = –55 to 130°C or TA = –40 to 85°C; VCC = 2.7V (except
where noted).
2. TJ = TA = 25°C.
3. Error accuracy is between the measured and calculated output voltage at specified conditions of voltage,
current, and temperature.
4. With negative current flowing into STLM20 and positive current flowing out, can typically sink less than 1µA
and source is 16µA.
5. Over the supply range of 2.4 to 5.5V.
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.
