Beschreibung von LP2992
The LP2992 is a fixed-output, wide-input, low-noise, low-dropout voltage regulator supporting an input voltage range from 2.5V to 16V and up to 250mA of load current. The LP2992 supports an output range of 1.2V to 5.0V (new chip).
Additionally, the LP2992 (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 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 LP2992 is available in a 5-pin 2.9mm × 2.8mm SOT-23 (DBV) package.
