LP2985A-25DBVR

LP2985 is a wide-input, fixed-output, low-noise, low-dropout regulator supporting an input voltage range of 2.5V to 16V and load currents up to 150mA. LP2985 supports an output range of 1.2V to 5.0V (for new devices). In addition, LP2985 (new devices) provides 1% output accuracy over the full load and temperature range, meeting the requirements of low-voltage MCUs and processors. Low output noise of 30µVRMS (with a 10nF bypass capacitor) and wide-bandwidth PSRR performance of greater than 70dB at 1kHz and greater than 40dB at 1MHz help attenuate the switching frequency of upstream DC/DC converters and minimize post-regulator filtering. Internal soft-start timing and current-limit protection reduce inrush current during startup, thereby minimizing input capacitance. Standard protection features such as overcurrent and overtemperature protection are also included. The LP2985 is available in a 5-pin 2.9mm × 1.6mm SOT-23 (DBV) package.
