SOT-23 (DBV)-5-8.12 mm² 2.9 x 2.8
The LP2980-ADJ is an adjustable-output, wide-input, low-dropout voltage regulator supporting an input voltage range up to 16 V and up to 50 mA of load current. The LP2980-ADJ supports an output range of 1.2 V to 15.0 V (new chip) and 1.23 V to 15.0 V (legacy chip).
Additionally, the LP2980-ADJ (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 of greater than 70 dB at 1 kHz and 45 dB at 1 MHz helps 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.
The LP2980-ADJ is available in a 5-pin, 2.9-mm × 1.6-mm SOT-23 (DBV) package.
