PBRC8.000BR-A(37 3P) Datasheet
A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application. Under all possible operating conditions, the junction temperature must be within the range specified under absolute maximum ratings. To determine if the heatsink is required, the power dissipated by the regulator, PD must be calculated. The below formula shows the voltages and currents for calculating the PD in the regulator: lin = IL / IG PD = (Vin-Vout) * IL + (Vin) * IG Ex. PD = (3.3V-2.5V) * 0.5A + 3.3V ' 11mA = 400mW + 36mW = 436mW Remark: IL iS output load current, IG iS ground current. Vin is input voltage Vout is output voltage

- LINEAR CURRENT LIMITER CIRCUIT: limits the drain current Id to llim whatever the Input pin voltage. When the current limiter is active, the device operates in the linear region, so power dissipation may exceed the capability of the heatsink. Both case and junction temperatures increase, and if this phase lasts long enough, junction temperature may reach the overtemperature threshold Tjsri.
