General Description
The TS9011 series is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent
current (30uA typ.), low dropout voltage, and high output voltage accuracy, making them ideal for battery applications.
The Chip Enable (CE) includes a CMOS or TTL compatible input allows the output to be turned off to prolong battery life.
The TS9001 series is included a precision voltage reference, error correction circuit, a current limited output driver, over
temperature shutdown, and a reference bypass pin to improve its already excellent low-noise performance.
This series are offered in 5-pin SOT-25 package.

Detail Description
Description
The TS9001 series of CMOS regulators contain a P-MOS pass transistor, voltage reference, error amplifier, over
current protection, thermal shutdown and short circuit protection.
The TS9001 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 1.05V, and reduces the current flow by 65%.
Full current is restored when the voltage exceeds 0.95V.
The internal P-channel pass transistor receives data from the error amplifier, over current shutdown, short output
protection 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 oC, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is
restored when the junction temperature drops below 120 oC.
Enable
The Chip Enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shut off, and all internal
circuits are powered down. In this state, the quiescent current is less than 5uA. This pin behaves much like an
electronic switch.
External Capacitor
The TS9001 series is stable with an output capacitor to ground of 2.2uF or greater. It can keep stable even with higher
or poor ESR capacitors.
A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be
larger than 0.1uF to have a beneficial effect.
A third capacitor can be connected between the Bypass pin and Ground. This capacitor can be a low cost polyester
film variety between the value of 1~10nF. A larger capacitor improves the AC ripple rejection, but also makes the
output come up slowly. This “soft” turn-on is desirable in some applications to limit turn-on surges.
All capacitors should be placed in close proximity to the pins. A “quiet” ground termination is desirable.
