TS5218
800mA Ultra Low Dropout
Voltage Regulator with Enable
General Description
The TS5218 is 800mA ultra low dropout linear voltage regulators that provide low voltage, high current output from
an extremely small package. These regulators offers extremely low dropout (typically 400mV at 800mA) and very low
ground current (typically 12mA at 800mA).
The TS5218 is 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.
Features
● Dropout voltage typically 0.4V @Io=800mA
● Output Current up to 800mA
● Low Ground Current
● Extremely Fast Transient Response
● Reversed Leakage & Reverse Battery Protection
● Current Limit & Thermal Shutdown Protection
