150mA µCap CMOS LDO Regulator w/Power Good

Micrel 

MIC5258

ground current is < 1% and can be ignored for this calculation.

315mW = (VIN – 1.2V) 150mA

315mW = VIN·150mA – 195mW

510mW = VIN·150mA

VIN(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 Regu-

lators 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.
