Texas Instruments LP2985-N Low-Dropout Voltage Regulators are fixed-output, wide-input, low-noise, low-dropout voltage regulators supporting an input voltage range from 2.5V to 16V and up to 150mA 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 30µV RMS (with 10nF bypass capacitors) and wide bandwidth PSRR performance of greater than 70dB at 1kHz and 40dB at 1MHz 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. The Texas Instruments LP2985-N comes in a 5-pin, 2.9mm × 1.6mm SOT-23 (DBV) package.
