LP2981IM5-5.0/NOPB | Texas Instruments
Voltage regulators, 2.5-5 V, 100 mA, positive, SOT-753, LP2981IM5-5.0/NOPB
NCNR (non cancelable / non returnable)
Low-Dropout Voltage Regulator, LP2981IM5-5.0/NOPB, Texas Instruments
The LP2981IM5-5.0/NOPB is a fixed-output, low-dropout (LDO) voltage regulator supporting an input voltage range from 2.5V to 16V and up to 100mA of load current. The LP2981IM5-5.0/NOPB supports an output range of 1.2V to 5.0V. Additionally, the LP2981-N has a ±1% output accuracy across load and temperature that can meet the needs of a low-voltage microcontroller (MCU) or processor. The LP2981IM5-5.0/NOPB provides wide bandwidth PSRR performance of 75dB at 1kHz and 45dB at 1MHz to help attenuate the switching frequency of an upstream DC/DC converter and minimize post-regulator filtering. The internal soft-start mechanism reduces inrush current during startup, thus minimizing input capacitance. Standard protection features, such as overcurrent and overtemperature protection, are included.
