Absolute Maximum Rating indicate limits beyond which damage to device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. TO-263 PKG TO-220 PKG Ordering Information Device(Marking) PKG LM1501AR-X.X TO-263 5L LM1501AT-X.X TO-220 5L FEATURES 3.3V, 5V, 12V, and adjustable output versions Adjustable version output voltage range, 1.23V to 37V ± 3% max over line and load conditions Guaranteed 5A output load current Input voltage range up to 40V Requires only 4 external components 150kHz ±15% fixed frequency internal oscillator Excellent line and Load regulation specifications Low power standby mode, IQ typically 80uA Thermal shutdown and current limit protection APPLICATION Simple high-efficiency step-down regulator On-card switching regulators Positive to negative converter DESCRIPTION X.X = Output Voltage = 3.3, 5.0, 12, ADJ The LM1501A series of regulators are monolithic integrated circuits that provide all the active functions for a step-down switching regulator, capable of driving a 5A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use. The LM1501A series operates at a switching frequency of 150kHz. Available in standard 5-lead TO-263 and TO-220 package. Other features include a guaranteed ± 3% tolerance on output voltage under specified input voltage and output load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 80uA standby current. Self protection features include a current limit for output switch and an over temperature shutdown for complete protection under fault conditions. The over temperature shutdown level is about 145℃ with 5℃ hysteresis. |
