AiT Semiconductor Inc. www.ait-ic.com A6303E CMOS LOW DROPOUT REGULATOR (LDO) 300mA UL TRA LOW POWER COM NSUMPTION REV1.0 - MAR 2020 RELEASED - - 9 - DETAILED INFORMATION Output Voltage The A6303E can provide output value of fixed version . The output voltage is s electable in 0.1V increments within the Range of 1.2V to 5V using trimming technologies. Short Protection Circuit The A6303E regulator offers circuit protection by means of a built -in foldback circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 60mA flows. EN Pin The IC's internal circuitry can be operated or shutdown via the signal from the EN pin with the A6303E. Note that the A6303E regulator is “High Active/No Pull -Down”, operations will become unstable with the EN pin open. We suggest that you use this IC with either a VIN voltage or a GND voltage input at the EN pin. If this IC is used with the correct specifications for the EN pin, the operational logic is fixed and the IC will operate normally. Otherwise, supply current may increase as a result of through current in the IC's internal circuitry. Thermal Shutdown When the junction temperature of the built -in driver transistor reaches the temperature limit, the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release voltage.
