Thermal design requires the follow- dropout voltage at full load makes them especially valu- ing application-specific parameters: Maximum ambient temperature, TA Output Current, IOUT Output Voltage, VOUT Input Voltage, VIN able in battery powered systems and as high efficiency noise filters in "post-regulator" applications. Unlike older NPN-pass transistor designs, where the minimum dropout voltage is limited by the base-emitter voltage drop and collector-emitter saturation voltage, dropout performance of the PNP output of these devices is limited merely by the low VCE saturation voltage. A trade- First, we calculate the power dissipation of the regulator from these numbers and the device parameters from this formula: PD = IOUT (1.01VIN - VOUT) off for the low dropout voltage is a varying base drive requirement. But, Gamma's PNP process reduces this drive requirement to merely 1% of the load current. where the ground current is approximated by 1% of IOUT. The GM66102 series of regulators are fully protected from damage due to fault conditions. Current limiting is Then the heat sink thermal resistance is determined with this formula: provided. This limiting is linear and output current under overload conditions is constant. Thermal shutdown RqSA = disables the device when the die temperature exceeds TJ(MAX) - TA PD (RqJC + RqCS) the 125°C maximum safe operating temperature. Transient protection allows device (and load) survival even when the input voltage spikes between -20V and where TJ(MAX) 125°C and RqCS is between 0 and 2°C/W. +60V. When the input voltage exceeds about 35V to 40V, the overvoltage sensor temporarily disables the regulator. The output structure of these regulators allows voltages in excess of the desired output voltage to be applied without reverse current flow. An additional feature of this regulator family is a common pinout: a design's current requirement may change up or down by yet use the same board layout, as all of these regu- The heat sink may be significantly reduced in applications where the minimum input voltage is known and is large compared with the dropout voltage. Use a series input resistor to drop excessive voltage and distribute the heat between this resistor and the regulator, the low dropout properties of Gamma PNP regulators allow very significant reductions in regulator power dissipation and the associated heat sink with- lators have identical pinouts. out compromising performance.
