LP2992 的說明
The LP2992 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 250 mA of load current. The LP2992 supports an output range of 1.2 V to 5.0 V (for 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 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 LP2992 is available in a 5-pin 2.9-mm × 2.8-mm SOT-23 (DBV) package.
