The SP6203 and SP6205 are ultra low noise CMOS LDOs with very low dropout and ground current. The noise performance is achieved by means of an external bypass capacitor without sacrificing turn-on and turn-off speed critical to portable applications. Extremely stable and easy to use, these devices offer excellent PSRR and line/load regulation. Target applications include battery powered equipment such as portable and wireless products. Regulators' ground current increases only slightly in dropout. Fast turn-on/turn-off enable control and an internal 30Ω pull down on output allows quick discharge of output even under no load conditions. Both LDOs are protected with current limit and thermal shutdown.
Both LDOs are available in fixed and adjustable output voltage versions and come in an industry standard 5-pin SOT-23 and small 2 x 3mm 8-pin DFN packages. For SC-70 100mA CMOS LDO, SP6213 is available.

Frequently Asked Questions
In this example, we looked for XRA1201. When you hover over it, it will turn grey and you can click anywhere in the grey box. This brings you to the product page. For example:
Click on Parts & Purchasing, highlighted in yellow above. The screen changes to:
Notice the status column and the “Show obsolete parts” link:
A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers:
Another method to find out if a part is OBS or EOL is to click on SUPPORT:
And then Product Change Notifications
Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:
If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
