LP38841MR-ADJ

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP38841MR-ADJ/NOPB is an adjustable low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a maximum output current of 800 mA with an input voltage range from 0.6 V to 35 V. The device features an adjustable output voltage ranging from 560 mV to 1.5 V, utilizing a negative bandgap reference for high accuracy. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 80 dB and a maximum dropout voltage of 75 mV at full load. The unit operates within a temperature range of -40°C to +125°C and is housed in an SO-PowerPad-8 surface-mount package.
