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
control. On the TS39154, the enable pin may be tied to V_IN if it is not required for enable control.
Features
● Dropout voltage typically 0.4V @ Io=1.5A
● Output Current up to 1.5A
● Low Ground Current
● Extremely Fast Transient Response
● Reversed Leakage & Reverse Battery Protection
● Internal Current Limit
