TS9001

300 mA CMOS LDO

Voltage Range 1.5 to 5.0 Volts

SOT-25

SOT-26

General Description

The TS9001 family of positive, linear regulators feature low quiescent current (30µA typ.) with low

dropout voltage, making them ideal for battery applications. The space-saving SOT-23-5 package is

attractive for “Pocket” and “Hand Held” applications.

These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure

under the “Worst” of operating conditions.

In applications requiring a low noise, regulated supply, place a 1000 pF capacitor between Bypass

and Ground.

The TS9001 is stable with an output capacitance of 2.2µF or greater.

be applied before a current source load is applied.

Detailed Description

The TS9001 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error

amplifier, over-current protection, and thermal shutdown.

The 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 120

o

C.

The TS9001 switches from voltage mode to current mode when the load exceeds the rated output

current. This prevents over-stress. The TS9001 also incorporates current foldback to reduce

power dissipation when the output is short circuited. This feature becomes active when the

output drops below 0.8volts, and reduces the current flow by 65%. Full current is restored when

the voltage exceeds 0.8 volts.

External Capacitors

The TS9001 is stable with an output capacitor to ground of 2.2µF or greater. Ceramic capacitors

have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic

capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large

value ceramic capacitors are comparatively expensive. One option is to parallel a 0.1µF ceramic

capacitor with a 10µF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low

overall cost.

A second capacitor is recommended between the input and ground to stabilize Vin. The input

capacitor should be at least 0.1µF to have a beneficial effect.

A third capacitor can be connected between the BYPASS pin and GND. This capacitor can be a

low cost Polyester Film variety between the value of 0.001 ~ 0.01µF. A larger capacitor improves

the AC ripple rejection, but also makes the output come up slowly. This "Soft" turn-on is desir-

able 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. This can be achieved with a "Star" connection.

Enable

The Enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shuts

off, and all internal circuits are powered down. In this state, the quiescent current is less than

1µA. This pin behaves much like an electronic switch.
