The LP2985-N is a fixed-output, wide-input, low-noise, low-dropout voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 150 mA of load current. The LP2985-N supports an output range of 1.2 V to 5.0 V (new chip) and 2.5 V to 6.1 V (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 30 µV RMS (with 10-nF bypass capacitors) and wide bandwidth PSRR performance of greater than 70 dB at 1 kHz and 40 dB at 1 MHz 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 LP2985-N is available in a 5-pin, 2.9-mm × 1.6-mm SOT-23 (DBV) package.

The LP2989LV is a fixed-output 500-mA precision LDO regulator designed for use with ceramic output capacitors. Output noise can be reduced to 18 µV (typical) by connecting an external 10-nF capacitor to the bypass pin. Using an optimized Vertically Integrated PNP (VIP) process, the LP2989LV delivers superior performance: Ground Pin Current: Typically 3 mA at 500-mA load, and 110 µA at 100-µA load. Sleep Mode: The LP2989LV draws less than 0.8-µA quiescent current whenSHUTDOWNpin is pulled low. ERRORFlag: The built-inERRORflag goes low when the output drops approximately 5% below nominal. Precision Output: Output voltage accuracy is 0.75% (A grade) and 1.25% (standard grade) at room temperature. For output voltages greater than or equal to 2 V, see the LP2989 (SNVS083) data sheet.
