Texas Instruments LP2980-ADJ Adjustable-Output Wide-Input Low-Dropout (LDO) Voltage Regulators support an input voltage range of up to 16V and up to 50mA load current. The LP2980-ADJ supports an output range of 1.2V to 15.0V (new chip) and 1.23V to 15.0V (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 70dB at 1kHz and 45dB at 1MHz 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 Texas Instruments LP2980-ADJ comes in a 5-pin, 2.9mm × 1.6mm SOT-23 (DBV) package.
