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.
