Frequently Asked Questions
What is the LP3985IM5-3.2/NOPB?
The LP3985IM5-3.2/NOPB is a 150mA low-noise LDO linear regulator from Texas Instruments with a fixed 3.2V output. It features ultra-low 30uVrms output noise, 75dB PSRR at 1kHz, a 300mV dropout voltage at full load, and an active-high enable pin. It operates from 2.5V to 5.5V input and is housed in a compact SOT-23-5 package.
What are the key specifications of the LP3985IM5-3.2/NOPB?
Key specs: Output voltage 3.2V fixed, maximum output current 150mA, dropout voltage 300mV at 150mA, input voltage range 2.5V to 5.5V, output noise 30uVrms from 10Hz to 100kHz, PSRR 75dB at 1kHz, operating temperature -40 to +125 degrees C, package SOT-23-5 with 5 pins.
What applications is the LP3985IM5-3.2/NOPB designed for?
The LP3985IM5-3.2/NOPB is designed for noise-sensitive applications including RF transceivers, wireless communication modules, LCD display panels, audio circuits, and portable IoT devices. Its low noise and high PSRR make it ideal for powering analog and RF subsystems from a 3.3V or Li-ion supply rail.
What are good alternatives or replacements for the LP3985IM5-3.2/NOPB?
Compatible alternatives include the TLV733P from TI with 300mA output in SOT-23-5, LP2985-3.2 from TI also at 150mA in SOT-23-5, and XC6206P322MR from Torex at 200mA in SOT-23-3. When substituting, verify output voltage, noise floor, PSRR, dropout voltage, and enable pin polarity.
Is the LP3985IM5-3.2/NOPB RoHS compliant and what does NOPB mean?
Yes, the LP3985IM5-3.2/NOPB is fully RoHS compliant and lead-free. NOPB stands for No Lead (Pb-free), confirming the device uses a lead-free tin finish on its package terminations, meeting EU RoHS Directive and similar international environmental regulations.
