Texas Instruments (LM3940IMP-3.3/NOPB) Fixed LDO Voltage Regulator

Fixed LDO Voltage Regulator, 0V to 7.5V, 500mV Dropout, 3.3Vout, 1Aout, SOT-223-3 Product Overview The LM3940IMP-3.3/NOPB is a 1A low-dropout Voltage Regulator, designed to provide 3.3V from a 5V supply. It is ideally suited for systems which contain both 5V and 3.3V logic, with prime power provided from a 5V bus. Because the LM3940IMP-3.3/NOPB is a true low-dropout regulator, it can hold its 3.3V output in regulation with input voltages as low as 4.5V. The LM3940IMP-3.3/NOPB means that in most applications the full 1A of load current can be delivered without using an additional heatsink. 4.5 to 5.5V Input Voltage Range Output Voltage Specified over Temperature Excellent Load Regulation Specified 1A Output Current Requires Only One External Component Built-in Protection Against Excess Temperature Short-circuit Protected Green Product, No Sb/Br Applications Power Management Product Information Output Type: Fixed Input Voltage Min: 0V Input Voltage Max: 7.5V Fixed Output Voltage Nom: 3.3V Output Current: 1A Dropout Voltage Vdo: 500mV LDO Regulator Case Style: SOT-223 No. of Pins: 3Pins Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: 3.3V 1A LDO Voltage Regulators
