TS9000/TS9000A
300mA CMOS Low Dropout Voltage Regulator
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.

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.
Over current and thermal shutdown circuits become active when the junction temperature exceeds 150
o
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
o
C.
