MIC5258_06 Datasheet, PDF (8/9 Pages) Micrel Semiconductor – 150mA μCap CMOS LDO Regulator w/Power Good

MIC5258
315mW = (V_IN – 1.2V) 150mA
315mW = V_IN·150mA – 195mW
510mW = V_IN·150mA
V_IN(max) = 3.4V
Therefore, a 1.2V application at 150mA of output current
can accept a maximum input voltage of 3.4V in a SOT-23-5
package. For a full discussion of heat sinking and thermal
effects on voltage regulators, refer to the Regulator Thermals
section of Micrel’s Designing with Low-Dropout Voltage
Regulators handbook.
Dual-Supply Operation
When used in dual supply systems where the regulator load
is returned to a negative supply, the output voltage must be
diode clamped to ground.
