TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. The DAP has no direct electrical wire connection to any of the eight pins. Negative feedback wikipedia 291, lookup. Alternatively, it may be programmed for any output voltage between its 1. Quiescent Current Figure A fold back feature limits the short-circuit current to protect the regulator from damage under all load conditions.
Low Battery Disconnect 9. Successfully implementing an LDO acm an application depends on the application requirements.

Switched-mode power supply wikipedialookup. Line Regulation Figure Control system wikipedialookup. Low Drift Current Source 9. TI may reference these types of products as “Pb-Free”. The junction-to-ambient thermal resistances are as follows: Furthermore, the quiescent current of the device increases only slightly in dropout, prolonging battery life. Note also that if a current limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO, resulting in a thermal shutdown of the output.
Place ground return connections to the input and output capacitor, and to the LDO ground pin as close to each other as possible, connected by a wide, component-side, copper surface. TI bases its knowledge and belief on information acmcc by third parties, and makes no representation or warranty as to the accuracy of such information.

LM2951-ACMC (IC Supply Chain)
In order to meet different application requirements, LPN can also be used as a programmable voltage regulator, with an external resistors network; please refer to Application and Implementation for more details. Because the Camc dropout voltage is load-dependent see curve in typical performance characteristicsthe input voltage trip point about 5 V varies with the load current.
If the requirements are simply input voltage and output voltage, compliance specifications such as internal power dissipation or stability must be verified to ensure a solid design. Information of third parties may be subject to additional restrictions. During a current-limit event, the LDO sources constant acnc.
If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance. At lower values of output current, less output capacitance is required for stability. Unless TI has accmc designated an individual product as meeting the requirements of a particular industry standard e. Device is in production to support existing customers, but TI does not recommend using this part in a new design. The use of vias and long traces to create LDO circuit connections is strongly discouraged and negatively affects system performance.
This grounding and layout scheme minimizes inductive parasitics, and thereby reduces acnc transients, minimizes noise, and increases circuit stability. Temperature of scmc Representative Units Figure 6. Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
LPN Enable Transient 9. Alternating current wikipedialookup. All linear dimensions are in millimeters. Three-phase electric power wikipedialookup. TI is not responsible or liable for such reproduced documentation.
Unlike many other regulators, the LPN remains stable acc in regulation with no load in addition to the internal voltage divider. Ohm’s law wikipedialookup. If timing, start-up, noise, PSRR, avmc any other transient specification is required, the design becomes more challenging. When FB is connected to ground, the pass element is fully turned on and out voltage will be close to input voltage. Refer to the block diagram in the front of the datasheet.

Load Transient Response Figure Efforts are underway to better integrate information from third parties. Quiescent Current Figure 2. Such equipment includes, without limitation, all medical devices identified by the U. For output capacitor requirement, please refer to Application and Implementation. Using products in an application does not by itself establish any safety features in the application. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources.
