The LP2985-N is a fixed-output, wide-input, low-noise, low-dropout voltage regulator. The device supports an input voltage range from 2.5V to 16V (new chip) and up to 150mA of load current. The LP2985-N supports an output range of 1.2V to 5.0V (new chip) and 2.5V to 6.1V (legacy chip). Additionally, the LP2985-N (new chip) has a ±1% output accuracy across load and temperature that can meet the needs of low-voltage microcontrollers (MCUs) and processors. Low output noise of 30µVRMS (with 10nF bypass capacitors) and wide bandwidth PSRR performance of greater than 70dB at 1kHz and 40dB at 1MHz (for new chip) help attenuate the switching frequency of an upstream DC/DC converter and minimize post regulator filtering. The new chip version of LP2985-N has internal soft-start mechanism that reduces inrush current during start up, thus minimizing input capacitance. Standard protection features, such as overcurrent and overtemperature protection, are included. The LP2985-N is available in a 5-pin, 2.9mm × 2.8mm SOT-23 (DBV) package.
