LM2991QML | 負(fù)低壓降可調(diào)節(jié)穩(wěn)壓器; ? Output voltage adjustable from ?2V to ?25V\n? Output current in excess of 1A\n? Dropout voltage typically 0.6V at 1A load\n? Low quiescent current\n? Internal short circuit current limit\n? Internal thermal shutdown with hysteresis\n? TTL, CMOS compatible ^ON/OFF switch \n? Functional complement to the LM2941 series; The LM2991 is a low dropout adjustable negative regulator with a output voltage range between ?2V to ?25V. The LM2991 provides up to 1A of load current and features a ^On /Off pin for remote shutdown capability. \n\n The LM2991 uses new circuit design techniques to provide a low dropout voltage, low quiescent current and low temperature coefficient precision reference. The dropout voltage at 1A load current is typically 0.6V and a guaranteed worst-case maximum of 1V over the entire operating temperature range. The quiescent current is typically 1 mA with a 1A load current and an input-output voltage differential greater than 3V. A unique circuit design of the internal bias supply limits the quiescent current to only 9 mA (typical) when the regulator is in the dropout mode (VO ? VI ≤?3V). \n\n The LM2991 is short-circuit proof, and thermal shutdown includes hysteresis to enhance the reliability of the device when inadvertently overloaded for extended periods. \n\n | TITexas Instruments 德州儀器美國德州儀器公司 | TI | |
