GM66300 Series 2010/3/2 3.0A ULTRA LOW DROPOUT VOLTAGE REGULATORS Typical Application Circuits The GM66300/01/02 is a high performance, low dropout voltage regulator suitable for moderate to high-current voltage regulator applications. Its 500mV dropout voltage at full load makes it especially valuable in battery-powered systems and a high-efficiency noise filter in post-regulator applications. Unlike older NPN-pass transistor designs, where the minimum dropout voltage is limited by the base-to-emitter voltage drop and collector-to-emitter saturation voltage, dropout performance of the PNP output of these devices is limited only by the low VCE saturation voltage. A trade-off for the low dropout voltage is a varying base drive requirement. Super beta PNP process reduces this drive requirement to only 2% to 5% of the load current. The GM66300/01/02 regulator is fully protected from damage due to fault conditions. Current limiting is provided. This limiting is linear, output current during overload conditions is constant. Thermal shutdown disables the device when the die temperature exceeds the maximum safe operating temperature. Transient protection allows device (and load) survival even when the input voltage spikes above and below nominal. The output structure of these regulators allows voltages in excess of the desired output voltage to be applied without reverse current flow. • Thermal design Linear regulators are simple to use. The most complicated design parameters to consider are thermal characteristics. Thermal design requires four application-specific parameters: • Maximum ambient temperature (TA) • Output Current (IOUT) • Output Voltage (VOUT) • Input Voltage (VIN) • Ground Current (IGND) Calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet, where the ground current is taken from data sheet PD = (VIN - VOUT) x IOUT + VIN x IGND The heat sink thermal resistance is determined by: θJA = TJ(max) – TA PD – (θJC +θCS) where TJ(max) ≤125°C and θCS is between 0°C and 2°C/W. The heat sink may by 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 Super βeta PNP regulators allow significant reductions in regulator power dissipation and the associated heat sink without compromising performance. When this technique is employed, a capacitor of at least 1.0µF is needed directly between the input and regulator ground. Refer to Application Note 9 for further details and examples on thermal design and heat sink specification. Output Capacitor The GM66300/1/2 requires an output capacitor to maintain stability and improve transient response. Proper capacitor selection is important to ensure proper operation. The GM66300/1/2 output capacitor selection is dependent upon the ESR (equivalent series resistance) of the output capacitor to maintain stability. When the output capacitor is 47µF or greater, the output capacitor should have less than 1. of ESR. This will improve transient response as well as promote stability. Ultra-low ESR capacitors, such as ceramic chip capacitors may promote instability. These very low ESR levels may cause an oscillation and/or underdamped transient response. A low-ESR solid tantalum capacitor works extremely well and provides good transient response and stability over temperature. Aluminum electrolytics can also be used, as long as the ESR of the capacitor is ≤1Ω. The value of the output capacitor can be increased without limit. Higher capacitance values help to improve transient response and ripple rejection and reduce output noise. GM66300V2.01 • 11 GM66300 Series 3.0A ULTRA LOW DROPOUT VOLTAGE REGULATORS • Input Capacitor An input capacitor of 1µF or greater is recommended when the device is more than 4 inches away from the bulk as supply capacitance, or when the supply is a battery. Small, surfacemount, ceramic chip capacitors can be used for the bypassing. Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage. • Transient Repsonse and 3.3V to 2.5V and 2.5V to 1.8V Conversions The GM66300/1/2 has excellent transient response to variations in input voltage and load current. The device has been designed to respond quickly to load current variations and input voltage variations. Large output capacitors are not required to obtain this performance. A standard 47µF output capacitor, preferably tantalum, is all that is required. Larger values help to improve performance even further. By virtue of its low-dropout voltage, this device does not saturate into dropout as readily as similar NPN-based designs. When converting from 3.3V to 2.5V or 2.5V to 1.8V, the NPN-based regulators are already operating in dropout, with typical dropout requirements of 1.2V or greater. To convert down to 2.5V without operating in dropout, NPN-based regulators require an input voltage of 3.7V at the very least. TheGM66300/1/2 regulator will provide excellent performance with an input as low as 3.0V or 2.5V. This gives the PNP-based regulators a distinct advantage over older, NPN-based linear regulators. • Minimum Load Current The MIC39300/1/2 regulator is specified between finite loads. If the output current is too small, leakage dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. • Error Flag The GM66301 version features an error flag circuit which monitors the output voltage and signals an error condition when the voltage drops 5% below the nominal output voltage. The error flag is an open-collector output that can sink 10mA during a fault condition. Low output voltage can be caused by a number of problems, including an over current fault (device in current limit) or low input voltage. The flag is inoperative during over temperature shutdown. When the error flag is not used, it is best to leave it open. The flag pin can be tied directly to pin 4, the output pin. • Enable Input GM66300V2.01 The GM66301/2 version features an enable input for on/off control of the device. Its shutdown state draws “zero” current (only microamperes of leakage). The enable input is TTL/CMOS compatible for simple logic interface, but can be connected to up to 20V. When enabled, it draws approximately 15µA. 12 GM66300 Series 2010/3/2 3.0A ULTRA LOW DROPOUT VOLTAGE REGULATORS Package Outline Dimensions – TO-263-5 0.390 - 0.410 (9.91 - 10.41) 0.260 - 0.280 (6.60 - 7.71) 0.050 (1.27) 0.175 - 0.183 (4.45 - 4.65) 0.048 - 0.052 (1.22 - 1.32) 0.330 - 0.350 (8.38 - 8.89) 0.565 max (14.35) max 7 3 0.090 - 0.110 (2.29 - 2.79) 0.015 - 0.030 (0.38 - 0.76) 0.028 - 0.038 (0.71 - 0.97) 0.057 - 0.077 (1.45 - 1.96) Package Outline Dimensions – TO-220-5 0.048 - 0.052 (1.22 - 1.32) 0.400 + 0.015 0.400 - 0.005 (0.38 + 0.18) (0.38 - 0.03) 0.240 - 0.260 (6.10 - 6.60) 0.175 - 0.185 (4.45 - 4.75) 0.100 - 0.120 (2.54 - 3.05) 0.149 - 0.153 (3.78 - 3.89) 0.330 - 0.350 (8.38 - 8.89) 0.525 - 0.555 (13.34 - 14.10) 0.030 - 0.040 (0.76 - 1.02) 0.057 - 0.077 (1.45 - 1.96) 0.105 + 0.010 0.105 - 0.010 0.015 + 0.007 0.015 - 0.001 (2.67 + 0.25) (2.67 - 0.38) (0.38 + 0.18) (0.38 - 0.03) GM66300V2.01 0.525 - 0.555 (13.34 - 14.10) 13 GM66300 Series 3.0A ULTRA LOW DROPOUT VOLTAGE REGULATORS Package Outline Dimensions – TO263 0.390 - 0.415 (9.906 - 10.541) 0.105 - 0.180 (4.191 - 4.572) 0.060 (1.524) TYP 0.045 - 0.055 (1.143 - 1.397) 15 TYP 0.330 - 0.370 (8.382 - 9.398) 0.059 (1.499) TYP 0.143 + 0.012 0.143 - 0.002 (3.632 + 0305) (3.362 - 0.508) 0.050 +/- 0.012 (1.270 +/- 0.305) 0.020 - 0.039 (0.510 - 0.990) GM66300V2.01 0.090 - 0.110 (2.286 - 2.794) 14 0.050 (1.270) 0.013 - 0.023 (0.330 - 0.584) GM66300 Series 2010/3/2 3.0A ULTRA LOW DROPOUT VOLTAGE REGULATORS Ordering Number GM 66300 -1.5 APM Gamma Micro Circuit Type TA3 R Output Voltage Package Type Shipping Type 1.8 2.5 3.3 5.0 TA3: TO263 TB3: TO220 R:Taping& Reel T: Tube TA5 R Output Voltage Package Type Shipping Type 1.8 2.5 3.3 5.0 TA5: TO263-5 TB5: TO220-5 R:Taping& Reel T:Tube = = = = 1.8V 2.5V 3.3V 5.0V GM 66301 -1.5 APM Gamma Micro Circuit Type = = = = 1.8V 2.5V 3.3V 5.0V GM 66302 -A Circuit Type R Output Voltage Package Type Shipping Type Adj TA3: TO263-5 TB3: TO220-5 R:Taping& Reel T:Tube Blank: Pb-free G:Green G Blank: Pb-free G:Green G Blank: Pb-free G:Green GM66300V2.01 APM Gamma Micro TA5 G 8 10 6 15
