TS9006

150mA Low Noise CMOS LDO

3/9 Version: A07

Application Information

Enable / Shutdown

The TS9006 comes with and active-high enable pin that allows the regulator to be enabled. Forcing the enable pin low

disables the regulator and puts it into the shutdown mode. This pin cannot be left floating as it may cause an

undetermined state.

Input / Output Capacitor

It is recommended to use a 0.47uF capacitor on the TS9006 input and a 0.47uF capacitor on the output. For high

regulation performance, larger input capacitor values and lower ESRs provide better noise rejection and line-transient

response. The output noise, load-transient response, stability, and power-supply rejection can be improved by using

large output capacitors. Low ESR ceramic capacitors provide optimal performance and save space.

Power Supply Rejection and Transient Response

The PSRR and transient response can be improved by increasing the values of the input and output bypass

capacitors, and through passive filtering techniques

Functional Description

Description

The TS9006 is an ultra-low-noise, low-quiescent current, low-dropout linear regulator. It is supplied in a SOT-25,

SOT-343 & DFN 2x2 package for difference applications. This device can supply loads up to 150mA. As shown in the

functional block diagram, the TS9006 consists of a reference and noise bypass circuit, error amplifier, output drive

transistor, internal feedback voltage divider, thermal sensor, and short circuit current limiter. The internal reference is

connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage

and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass=transistor gate is

pulled low. This allows more current to pass to the output and increases the output voltage.

Stability

The TS9006 is a high performance LDO emphasizing stability with low output capacitance. It is able to maintain

stability with an output capacitor can also be increased to optimize performance. The TS9006 will remain stable and in

regulation with no load, unlike many other voltage regulators.

Internal P-Channel Pass Transistor

The TS9006 features allow impedance P-channel MOSFET pass transistor. This provides several advantages over

similar designs using a PNP pass transistor, including low operating power and longer battery life. The TS9006

consumes only 90µA of quiescent current under most conditions.

Output Short-Circuit Current Limit

The TS9006 includes a current limiter, which monitors and controls the pass transistor’s gage voltage, limiting the

output current to about 200mA, for example, in a short-circuit output situation.

Shutdown

The TS9006 also features a low-power active shutdown mode. It has a switch that turns off the device when disabled.

This allows the output capacitor and load to discharge and de-energize the load. In the shutdown mode, the internal

functional blocks, such as voltage reference and the error amplifier, are turned off completely, and the quiescent

current is less than 1µA.
