| Description GM66102 of positive fixed and adjustable regulators is designed to provide up to 1A output with high current, high accuracy, and extremely low dropout voltage performance. These regulators feature 300 to 350mV (full load) dropout voltages and very low ground current. Although designed for high current, and loads, these devices are also useful in lower current, extremely low dropout-critical systems, where their minimal dropout voltage and ground current values are important characteristics. GM66102 is fully protected against overcurrent, reversed input polarity (or reversed battery connection), reversed lead insertion, over-temperature operation, and transient voltage spikes (positive or negative). GM66102 is available in TO-220, SOT-223, TO-252 and TO-263 packages.

GM66102-3.3 Output Voltage vs. Temperature APPLICATION INFORMATION GM66102 series is high performance whit low-dropout voltage regulators, suitable for all moderate to highcurrent voltage regulator applications. Their 350mV dropout voltage at full load makes them especially valuable 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 tradeoff 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. The GM66102 series of regulators are fully protected from damage due to fault conditions. Current limiting is provided. This limiting is linear and output current under overload conditions is constant. Thermal shutdown disables the device when the die temperature exceeds the 125C maximum safe operating temperature. Transient protection allows device (and load) survival even when the input voltage spikes between -20V and +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 regulators have identical pinouts. VIN + Thermal Design Linear regulators are simple to use. The most complicated design parameters to consider are thermal characteristics. Thermal design requires the following application-specific parameters: Maximum ambient temperature, TA Output Current, IOUT Output Voltage, VOUT Input Voltage, VIN First, we calculate the power dissipation of the regulator from these numbers and the device parameters from this formula: PD = IOUT (1.01VIN - VOUT) where the ground current is approximated by 1% of IOUT. Then the heat sink thermal resistance is determined with this formula: TJ(MAX) - TA PD RqSA = (RqJC + RqCS) where TJ(MAX) 2C/W. 125C and RqCS is between 0 and 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 without compromising performance. When this tech- VIN GND VOUT + VOUT nique is employed, a capacitor of at least 0.1F is needed directly between the input and regulator ground. Figure 9. Linear regulators require only two capacitors for operation.
