1 / 24 page  2018 - 2022 Microchip Technology Inc. and its subsidiaries DS20006017B-page 1 MIC39300/01/02 Features • 3.0A Minimum Guaranteed Output Current • 550 mV Maximum Dropout Voltage over Temperature • Ideal for 3.0V to 2.5V Conversion • Ideal for 2.5V to 1.8V Conversion • 1% Initial Accuracy • Low Ground Current • Current Limiting and Thermal Shutdown • Reversed-Battery Protection • Reversed-Leakage Protection • Fast Transient Response • TO-263 (D2Pak) and TO-220 Packaging • TTL/CMOS Compatible Enable Pin (MIC39301/2 Only) • Error Flag Output (MIC39301 Only) • Adjustable Output (MIC39302 Only) Applications • LDO Linear Regulator for PC Add-In Cards • High-Efficiency Linear Power Supplies • SMPS Post Regulator • Multimedia and PC Processor Supplies • Low Voltage Microcontrollers • StrongARM Processor Supply General Description The MIC39300, MIC39301, and MIC39302 are 3.0A low-dropout linear voltage regulators that provide a low voltage, high-current output with a minimum of external components. Utilizing Microchip’s proprietary Super βeta PNP pass element, the MIC39300/1/2 offers extremely low dropout (typically 385 mV at 3.0A) and low ground current (typically 36 mA at 3.0A). The MIC39300/1/2 are ideal for PC add-in cards that need to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 500 mV over all operating conditions allows the MIC39300/1/2 to provide 2.5V from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The MIC39300/1/2 also have fast transient response for heavy switching applications. The device requires only 47 µF of output capacitance to maintain stability and achieve fast transient response. The MIC39300/1/2 are fully protected with overcurrent limiting, thermal shutdown, reversed-battery protection, reversed-leakage protection, and reversed-lead insertion. The MIC39301 offers a TTL-logic compatible enable pin and an error flag that indicates undervoltage and overcurrent conditions. Offered in fixed voltages, the MIC39300/1 come in the TO-220 and TO-263 (D2Pak) packages and are an ideal upgrade to older, NPN-based linear voltage regulators. The MIC39302 adjustable option allows programming the output voltage anywhere between 1.24V and 15.5V and is offered in a 5-Pin TO-263 (D2Pak) package.
