LM2931CT Datasheet

PMIC - Voltage Regulators - Linear (LDO)


The LM2931CT series consists of positive fixed and adjustable outputvoltage regulators that are specifically designed to maintain properregulation with an extremely low input&minus;to&minus;output voltage differential.These devices are capable of supplying output currents in excess of100 mA and feature a low bias current of 0.4 mA at 10 mA output.Designed primarily to survive in the harsh automotive environment,these devices will protect all external load circuitry from input faultconditions caused by reverse battery connection, two battery jumpstarts, and excessive line transients during load dump. This series alsoincludes internal current limiting, thermal shutdown, and additionally,is able to withstand temporary power&minus;up with mirror&minus;image insertion.Due to the low dropout voltage and bias current specifications, the LM2931CT series is ideally suited for battery powered industrial andconsumer equipment where an extension of useful battery life isdesirable. The &lsquo;C&rsquo; suffix adjustable output regulators feature an outputinhibit pin which is extremely useful in microprocessor&minus;based systems. LM2931CT Features &bull; Input&minus;to&minus;Output Voltage Differential of < 0.6 V @ 100 mA&bull; Output Current in Excess of 100 mA&bull; Low Bias Current&bull; 60 V Load Dump Protection&bull; &minus;50 V Reverse Transient Protection&bull; Internal Current Limiting with Thermal Shutdown&bull; Temporary Mirror&minus;Image Protection&bull; Ideally Suited for Battery Powered Equipment&bull; Economical 5&minus;Lead TO&minus;220 Package with Two Optional Leadforms&bull; Available in Surface Mount SOP&minus;8, D2PAK and DPAK Packages&bull; High Accuracy (&plusmn;2.5%) Reference (LM2931AC) Available&bull; Pb&minus;Free Packages are Available LM2931CT Applications &bull; Battery Powered Consumer Products&bull; Hand&minus;held Instruments&bull; Camcorders and Cameras
