Point Regulators (Low-Dropout Regulator)
The TAR5SBxx Series is comprised of general-purpose bipolar
single-power-supply devices incorporating a control pin which can
be used to turn them ON/OFF.
Overtemperature and overcurrent protection circuits are built
into the devices' output circuit.
Features
Low stand-by current
Over-temperature/over-current protection
Operation voltage range is wide.
Maximum output current is high.
Low dropout voltage
Small package (SOT-23 5 pin)
Ceramic capacitors can be used.
Pin Assignments
(top view)
Over-temperature/over-current protection functions are NOT guarantee maximum-ratings of these devices.
Do not use devices under conditions in which their maximum ratings will be exceeded.
