= 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 Regu-
latorshandbook.
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.
