(PPAK)

General Description

TS39154 is 1.5A ultra low dropout linear voltage regulators that provide low voltage, high current output from an

extremely small package. This regulator offers extremely low dropout (typically 400mV at 1.5A) and very low ground

current (typically 25mA at 1.5A). TS39154 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
