Detail Description
Description
The TS9002 series of CMOS regulators contain a P-MOS pass transistor, voltage reference, error amplifier, over
current protection, thermal shutdown and power good function.
The TS9002 series switches from voltage mode to current mode when the load exceeds the rated output current. This
prevents over stress. The TS9002 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, 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
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 120
o
C.
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 1uA. This pin behaves much like an
electronic switch.
External Capacitor
The TS9002series 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.
All capacitors should be placed in close proximity to the pins. A “quiet” ground termination is desirable.
Power Good
The TS9002 includes the Power Good feature. When the output is not within = +/-15% of the specified voltage, it pulls
low. This can occur on other condition – input voltage too low, during over-temperature, during over-current and
output is pulled up.
