TS5205_1 Datasheet, PDF (3/6 Pages) Taiwan Semiconductor Company, Ltd – 150mA Low Noise LDO Voltage Regulator with Enable

Electrical Characteristics (continued)
Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The maximum allowable power dissipation at any Ta is Pd(max) = [ Tj(max) - Ta] + Ó¨ja. Exceeding the
maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into
thermal shutdown.
Note 3: The device is not guaranteed to function outside its operating rating.
Note 4: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
for load regulation in the load range from 1mA to 150mA. Changes in output voltage due to heating effects
are covered by the thermal regulation specification.
Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
Note 7: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current
drawn from the supply is the sum of the load current plus the ground pin current.
Note 8: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation
is applied, excluding load or line regulation effects. Specifications are for a 150mA load pulse at Vin=16V for
t=10mS.
