1.0A Ultra Low Dropout Positive Voltage Regulator Low Dropout Voltage 0.4V (typ.) Enable Input Control Adjustable Output Error Flag Detection

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 TS39301/2/3/4 are 3A ultra low dropout linear voltage regulators that provide low voltage, high current output with a minimum of external components. The TS39301/2/3/4 offers extremely low dropout (typically 400mV at 3A) and low quiescent current (typically 36mA at 3A). The TS39301/2/3/4 is ideal for PC add-in cards that need to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the TS39301/2/3/4 to provide 2.5V from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The TS39301/2/3/4 also has fast transient response for heavy switching applications. The device requires only 47uF of output capacitor to maintain stability and achieve fast transient response.
