TS29100

TS29100/1/2 1.0A Ultra Low Dropout Positive Voltage Regulator Low Dropout Voltage 0.4V typ. Enable Input Control Adjustable Output Error Flag Detection General Description The TS29100/1/2 series are using process with a PNP pass element for high current, high accuracy and low dropout voltage regulators. These regulator s feature 400mV(typ) dropout voltages and very low ground current, these devices also find applications in lower current and low dropout critical systems, where their tiny dropout voltage and ground current values are important attributes. The TS29100/1/2 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 TS29101 and TS29102, 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 and 8-pin SOP pacakge. Features Dropout voltage typically 0.4V @Io=1.0A Output current up to 1.0A Low ground current Output voltage trimmed before assembly Extremely fast transient response +60V Transient peak voltage -20V Reverse peak voltage Zero current shutdown mode Error flag signals output out of regulation Internal current limit Thermal shutdown protection Ordering Information Part No. TS29100CWxx TS29101CSxx TS29102CSxx TS29102CS Note: Where xx denotes voltage option, available are 12V, 5.0V, 3.3V and 2.5V.
