LT3094HMSE#PBF

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

The LT3094HMSE#PBF is a negative linear regulator from Analog Devices, housed in a 12-lead MSOP package. It delivers 500mA output current with an input voltage range of –20V to –2.3V and an adjustable output voltage spanning 0V to –19.5V. The device features ultralow noise performance, achieving 0.8µVRMS between 10Hz and 100kHz, and maintains high power supply rejection ratio (PSRR) of 74dB at 1MHz. Operating junction temperature extends up to 150°C, with quiescent current dropping to 3µA during shutdown.
