LP2985AIM5-5.0  5V, 150mA, Low-Noise, Ultra-Low-Dropout Voltage Regulator with Enable
Item # 20352
5.0V  150mA Low Noise LDO Voltage Regulator


Fixed Output Voltage: 5.0V
Package type: SOT-23-5
Description: 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 is a linear voltage regulator operating from 2.5 V to 16 V on the input and regulates voltages

The LP2985AIM5-5.0 output voltage is 5.0V. 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 μVRMS (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.
