TAR5S15~TAR5S50
TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TAR5S15~TAR5S50
Point Regulators (Low-Dropout Regulator)
The TAR5Sxx 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
in to the devices’ output circuit.
Features
•
Low stand-by current
•
Overtemperature/overcurrent protection
•
Operation voltage range is wide.
•
Maximum output current is high.
•
Difference between input voltage and output voltage is low.
•
Small package.
•
Ceramic capacitors can be used.
Weight: 0.014 g (typ.)
