TS9010 series 3-4 2004/09 rev. C Electrical Characteristics (continued) Note 1: Exceeding the absolute maximum rating may damage the device. Note 2: The device is not guaranteed to function outside its operating rating. Note 3: The maximum allowable power dissipation at any Ta is Pd(max) = [ Tj(max) - Ta] * Өja. Exceeding the maximum allowable power dissipation will result in exce ssive die temperature, and the regulator will go into thermal shutdown. Note 4: Output voltage tem perature coefficient is defi ned 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( Vout>2.5V) and 1mA to 80mA(Vout<2.5V). Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 6: Dropout voltage is defined as t he input to output differential at whic h the output voltage dr ops 2% below its nominal value measured at 1V differential. Note 7: Ground pin current is the regulat or quiescent current plus pass transisto r 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=12V for t=10mS. Application Examples Standard Circuit Typical Application Circuit 2
