Unlike older regulators with a single junction-to-case thermal resistance specification, the data section for these new regulators provides a separate thermal resistance and maximum junction temperature for both the Control Section and the Power Transistor.

F solid tantalum on the output will ensure stability for all operating conditions. Thermal Considerations The AMS series have internal power and thermal limiting circuitry designed to protect the device under overload conditions.

Protection Diodes Unlike older regulators, the AMS family does not need any protection diodes between the adjustment pin and the output and from the output to the input to prevent over-stressing the die.

Unlike older regulators with a single junction-to-case thermal resistance specification, the data section for these new regulators provides a separate thermal resistance and maximum junction temperature for both the Control Section and the Power Transistor.

The data sheet specification for load regulation is measured at the bottom of the package.

Can flash at 2 Hz during fast forward. Placing a resistor between these two terminals causes a constant current to flow through R1 and down through R2 to set the overall output voltage.

AMSCD from Advanced Monolithic Systems Inc. (AMS)

Datasheeh surge currents of 50A to A can as1085 handled by the internal diode between the input and output pins of the device. Using gauge wire the parasitic line resistance is about 0. The size of the required adjust pin capacitor is a function of the input ripple frequency.

As with any IC regulator, none the protection circuitry will be functional and the internal transistors will break down if the maximum input to output voltage differential is exceeded. In normal operations it is difficult to get those values of surge currents even with the use of large output capacitances.

The data sheet specification for load regulation is measured at the bottom of the package. Ripple Rejection The ripple rejection values are measured with the adjustment pin bypassed.

At 10kHz only 0. F aluminum covers all cases of bypassing the adjustment terminal. Advanced Monolithic Systems, Inc. Disclaimer Devices sold by ams AG are covered by the warranty and patent indemnification provisions appearing in its Term of Sale. The device features a 1.

Maximum Allowable Power Dissipation W 2. During the start-up, as the input voltage is rising, the input-to-output voltage differential remains small, allowing the regulator to supply large output currents.

The ripple rejection will be a function of output voltage, in circuits without datashedt adjust pin bypass capacitor. F aluminum electrolytic or a 22?

See thermal regulation specifications for changes in output voltage due to heating effects. Calculations for both temperatures under certain conditions of ambient temperature and heat sink resistance and to ensure that both thermal limits are met. The resistance of the wire connecting the regulator to the load will limit the load regulation. Dtasheet Overload Recovery When the power is first turned on, as the input voltage rises, the output follows the input, permitting the regulator to start up into heavy loads.

With this double intersection, asm1085 power supply may need to be cycled down to zero and brought up again datahseet make the output recover. To ensure safe operating temperatures and reflect more accurately the device temperature, new thermal resistance specifications have been developed. Thermal Considerations The AMS series have internal power and thermal limiting circuitry designed to protect the device under overload conditions.

To further datashedt stability and transient response of these devices larger values of output capacitor can be used. Dropout voltage is specified over the full output current range of the device. Internal resistors are limiting the internal current paths on the AMS adjustment pin, therefore even with capacitors on the adjustment pin no protection diode is needed to ensure device safety under short-circuit conditions.

Post Regulators for Switching Supplies? A thermally conductive spacer can be used, if the case of the device must be electrically isolated, but its added contribution to thermal resistance has to be considered.

If high value output capacitors are used, such as ? The best load regulation is obtained when the top of the resistor divider R1 is connected directly to the case not to the load. F Overload Recovery When the dattasheet is first turned on, as the input voltage rises, the output follows the datassheet, permitting the regulator to start up into heavy loads.

Ripple Rejection The ripple rejection values are measured with the adjustment pin bypassed. FR ic transistor FR 8 pin Text: This is ama1085 lowest resistance path for the heat flow. Thermal compound at the case-to-heat sink interface is recommended. If it is unable. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. General Description This guide .
