Description for the LP2981

The LP2981 is a fixed-output, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V (for new chip only) and up to 100 mA of load current. The LP2981 supports an output range of 1.2 V to 5.0 V (new chip).

Additionally, the LP2981 (new chip) has a 1% output accuracy across load and temperature that can meet the needs of low-voltage microcontrollers (MCUs) and processors.

In the new chip, wide bandwidth PSRR performance is 75 dB at 1 kHz and 45 dB at 1 MHz to help attenuate the switching frequency of an upstream DC/DC converter and minimize post regulator filtering.

The internal soft-start time and current-limit protection reduce inrush current during start up, thus minimizing input capacitance. Standard protection features, such as overcurrent and overtemperature protection, are included.

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.
