Description for the LP5952

The LP5952 is a dual-supply-rail linear regulator optimized for powering ultralow-voltage circuits from a single Li-Ion cell or 3-cell NiMH/NiCd battery.

In the typical post-regulation application VBATT is directly connected to the battery (range 2.5 V to
5.5 V), and VIN is supplied by the output voltage of the DC-DC converter (range 0.7 V to 4.5 V).

The device offers superior dropout and transient features combined with very low quiescent currents. In shutdown mode (Enable (EN) pin pulled low) the device turns off and reduces battery consumption to 0.1 µA (typical). The LP5952 also features internal protection against overtemperature, overcurrent, and undervoltage conditions.

Depending upon application, only one or two tiny surface-mount external components are required; performance is specified for a –40°C to +125°C junction temperature range. The device is available in fixed output voltages from 0.5 V to 2 V. For availability, please contact your local Texas Instruments sales office.

For all available packages, see the orderable addendum at the end of the data sheet.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
