Application Information
It is recommended to use a 0.47uF capacitor on the TS9005/A 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 Function Description
Description
The TSS005/A is an ultra-low-noise, low-quiescent current, low-dropout linear regulator. It is supplied in a SOT-25 package for difference applications. This device can supply loads up to 600mA. As shown in the functional block diagram, the TSS005/A 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 TS9005/A 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 TS9005/A will remain stable and in regulation with no load, unlike many other voltage regulators. Internal P-Channel Pass Transistor The TS9005/A features a low 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 TS9005/A consumes only 100\\A of quiescent current under most conditions. Output Short-Circuit Current Limit The TS9005/A includes a current limiter, which monitors and controls the pass transistor’s gage voltage, limiting the output current to about 420mA, for example, in a short-circuit output situation. Shutdown The TS9005/A 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 1pA. Thermal Protection Shutdown The thermal protection shutdown function protects the device from operating in over temperature condition. When the junction temperature exceeds +1600C, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to tool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops to +1400C. Soft-Start Circuitry The TS9005/A includes a soft-start circuitry to limit inrush current at turn-on. During power up, the output capacitor and output load are charged with a reduce output current. Shortly after the initial power up, the soft-start feature is terminated and normal operation is resumed. 3/7 Version: BO7
