Ultra low dropout voltage. The LP is a mA, fixed-output voltage regulator. Guaranteed mA output current. L2p985 minimum external components. Stable with dafasheet output capacitor. A quiescent current when shut down. Typically mV lp9285 load, and. Low ground pin current at all loads. A mA load, and. High peak current capability. A 1 mA load. Wide supply voltage range 16V max. The LP is stable with output ca. C junction temperature range. OFF pin is pulled low.

By adding a 10 nF bypass capacitor, output. Camcorder, Personal Stereo, Camera. Multiple voltage options, from 2. Consult factory for custom voltages. Tie to V IN if this function is not to be used. Ceramic capacitor required for output see Application Hints.

Use ceramic or film type with very low leakage current see Application Hints. For ordering information see Table 1.

The actual physical placement of the package marking will vary from. Package marking contains date code and lot traceability. Package marking does not correlate. Common Ground device substrate.

Input Supply Voltage Operating. Shutdown Input Voltage Survival. Distributors for availability and specifications. Output Voltage Survival, Note 4. ESD Rating Note 2. Power Dissipation Note 3. Electrical Characteristics Note Electrical specifications do not apply when operating the. The maximum allowable power dissipation at any ambient temperture is calculated using: For 12V option, output voltage survival: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control.

Dropout voltage is defined as the input to output differential at which the output voltage drops mV below the value measured with a 1V differential.

For details, refer to Application Hints. Exposing the micro SMD device to direct sunlight will cause misoperation. See Application Hints for additional information.

Ground Pin vs Load Current. Dropout Voltage vs Temperature.

Input Current vs Pin. Instantaneous Short Circuit Current. It should be noted that. Like any low-dropout regulator, the LP requires external. These capacitors must be. The output capacitor must be located not more than 1 cm. Connecting a 10 nF capacitor to the Bypass datssheet significantly.

This capacitor must be l2p985 a distance of not more than 1. Any good quality ceramic, tantalum, or film capacitor may be. Because this circuit has only a few microamperes flowing in. Tantalum capacitors can suffer catastrophic fail. For this reason, DC leakage. If a Tantalum capacitor is used at the input, it. The types of capacitors best suited for the noise bypass. There are no requirements datashfet ESR on the input capacitor.

F over the entire operating temperature range. The LP is designed specifically to work with ceramic. The LP was designed to work with ceramic capacitors. The ESR of a typical 2. The output capacitor must meet the requirement for datashfet.

One disadvantage of ceramic capacitors is that their capaci. Most large value ceramic. Curves are provided which show the stable ESR range as a. F are manufactured with the Z5U or Y5V.

This could cause problems if a 2. F capacitor were used. If Z5U or Y5V capacitors are used on the output. F must be observed. A better choice for temperature coefficient in ceramic capaci. Tantalum capacitors are less desirable than ceramics for use. The output capacitor must maintain its ESR. Another important consideration is that Tantalum capacitors. The LP requires a minimum of 2. F on the output.

It is datqsheet to remember that capacitor tolerance and. It should also be noted that the ESR of a typical Tantalum will. In any application where the output may be pulled above the. C, so some guard band must be allowed.

If this feature is not to be used. The micro SMD package requires dataheet mounting tech. To assure proper datashete, the signal source used to drive. Referring to the section Surface Mount.
