TS5218

800mA Ultra Low Dropout

Voltage Regulator with Enable

1/7

Version: A09

TDFN 3x3

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.
