General Description
The TS9000/TS9000A series is a positive voltage regulator developed utilizing CMOS technology featured low quiescent
current, low dropout voltage and high output voltage accuracy. Built in low on-resistor provides low dropout voltage and
large output current. A 2.2uF or greater can be used as an output capacitor.
The TS9000/TS9000A series are prevented device failure under the worst operation condition with both thermal
shutdown and current fold-back. These series are recommended for configuring portable devices and large current
application, respectively.
This series are offered in 3-pin TO-92, SOT-89 and SOT-23 package.
Features
Dropout voltage typically 0.4V @Io=300mA
Output current up to 300mA
Low quiescent current

Detail Description
The TS9000/TS9000A series of CMOS regulators contain a P-MOS pass transistor, voltage reference, error amplifier,
over current protection and thermal shutdown.
The TS9000/TS9000A series switches from voltage mode to current mode when the load exceeds the rated output
current. This prevents over stress. The TS9000 also incorporates current fold-back to reduce power dissipation when
the output is short circuit. This feature becomes active when the output drops below 0.8V, and reduces the current flow
by 65%. Full current is restored when the voltage exceeds 0.8V.
The internal P-channel pass transistor receives data from the error amplifier, over current shutdown and thermal
protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference.
o
Over current and thermal shutdown circuits become active when the junction temperature exceeds 150 C, or the
current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when
the junction temperature drops below 110
