ACT Datasheet PDF – Motorola => Freescale

These capacitors should be placed close to the terminals for them to work effectively. The list of “features” of the chip states “internal voltage reference” but other than this statement and datashee list of settings, I see no mention of it whatsoever in the datasheet, errata, or app notes.

This 7 Watts will be dissipated as heat.

Note that the feedback into the shunt regulator comes from the regulated output of the power supply. D Moving Display Board. In applications requiring a different output voltagethe characteristics of the chosenexample: LM Voltage Regulator Datasheet. In fact, there IS a voltage reference mentioned in the electrical specifications, but it appears to be something completely different: High Input Voltage datashete, Figure The module requires a 3.

I suspect that others now make similar regulators in lower voltages but I don’t have manufacturers or part numbers handy. Hi all, This problem is driving me crazy: C7, C8, C9 and C10 are filter capacitors. Its range of applications are large and can include digitalinitiate different walking effect types. The IC measures voltage and currentcontinuously measuring the instantaneous voltage V and current A and finding the product of these to give.

Thank-you to Joe datashwet all who answered. Sean On Wed, Nov 16, at 7: Submitted by admin on 30 August They provide a constant output voltage for a varied input voltage. I do most of my designs such that the 5V rail has to supply only a tiny amount of current: These devices offer voltage regulation at extremely low cost.

This IC can also act as an adjustable output voltage regulator, meaning you can also control the output voltage for your desired value using the below circuit. You mention automotive – a reasonable number of my designs are used in either automotive or industrial machinery 24V rail nominal.

The cheap versions do need about 1mA to regulate well.

Sloppy documentation by the look of it Oh. Its sharp turn-on characteristics and flexible output voltage setting make it an excellent replacement for Zener diodes in many applications. Another option is to use a low-cost shunt reference such as the LM, which will give you 2.

Instead, think of using a voltage reference for your main voltage regulator assuming you don’t need high current. The value can be calculated using the below formulae.

Try Findchips PRO for voltage regulator applications. If your circuit uses a small 78L05 regulator as is shown in 7805acr 9 of the ELM data sheetwe recommend that you change it to a larger type regulator. Its range of applications are large dattasheet can include digital clockswill initiate different walking effect types. As noted, you can get good accuracy fairly cheaply. When ordering, replace the 00 with the appropriate voltage level, eg.

We show, be sure that your 5V supply uses a type regulatorand not a 78L05 type. YD is an adjustable precision shunt regulator. Best regards, Spehro Pefhany –“it’s the network Voltage regulators are very common in electronic circuits.
