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.
