The LP3982ILDX-ADJ\/NOPB is a 300 mA ultra-low-dropout CMOS LDO regulator from Texas Instruments with adjustable output voltage. Packaged in an 8-pin WSON (NGM), it operates from 2.5 V to 6 V input and offers output voltage adjustable from 1.25 V to 6 V. The device features low noise (37 \u00b5Vrms), high PSRR (60 dB), and a power-good flag, making it ideal for noise-sensitive analog and RF applications.<\/p>\n

Available in adjustable and fixed voltage versions, the device is pin- and package-compatible with the Maxim MAX8860. The PMOS pass transistor provides very low dropout voltage and consumes negligible drive current compared to PNP-based LDOs. The adjustable version uses an external resistor divider to set the output voltage from 1.25 V to 6 V. With 37 \u00b5Vrms output noise and 60 dB PSRR, the LP3982 is ideal for noise-sensitive RF and analog circuits.","working_principle":"The LP3982 uses a PMOS pass transistor in a feedback-regulated LDO topology. The output voltage is sensed through an external resistor divider (adjustable version) and compared against an internal 1.25 V bandgap reference by the error amplifier. The error amplifier drives the PMOS gate to maintain regulation. A noise bypass capacitor on the CC pin filters the bandgap reference, reducing output noise to 37 \u00b5Vrms. The FAULT pin provides an open-drain power-good indicator that pulls low when the output drops out of regulation. The SHDN pin enables\/disables the regulator with 1 nA shutdown current.","pin_description":"
