The TS39100/1/2/3 series are 1A ultra low dropout linear voltage regulators that provide low voltage, high current output from an extremely small package. These regulator offers extremely low dropout (typically 400mV at 1A) and very low ground current (typically 12mA at 1A). The TS39100/1/2/3 series are fully protected against over current faults, reversed input polarity, reversed lead insertion, over temperature operation, positive and negative transient voltage spikes, logic level enable control and error flag which signals whenever the output falls out of regulation. On the TS39101/2/3, the enable pin may be tied to Vin if it is not required for enable control. This series are offered in 3-pin SOT-223 (TS39100), 8-pin SOP (TS39101/2) and 5-pin TO-252 (TS39103) package.
The document describes the TS39100/1/2/3 series as 1A ultra low dropout linear voltage regulators designed to provide low voltage, high current output from an extremely small package. These devices feature a typical dropout voltage of 400mV at 1A and offer protection against over-current faults, reversed input polarity, and thermal shutdown.
