Input 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 Output voltage trimmed before assembly Internal current limit Thermal shutdown protection Ordering Information Part No. TS9000xCT TS9000xCY Battery power equipment Personal communication devices Home electronic appliances PC peripherals CD-ROM Digital signal camera SOT-23 o -40 ~ +85 C SOT-89 TS9000AxCT TO-92 TS9000AxCX SOT-23 TS9000AxCY SOT-89 Note: Where x denotes voltage option, available are K=2.5V, M=2.7V, N=2.8V, P=3.0V, S=3.3V, U=3.5V, V=3.6V, X=3.8V.

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 oC. TS9000/A series 2-4 2003/12 rev.
