LT3015IMSE#PBF

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

The LT3015IMSE#PBF is a negative linear regulator from Analog Devices, housed in a 12-lead MSOP package. It delivers up to 1.5A of output current with a typical dropout voltage of 310mV. The device operates within an input voltage range of -1.8V to -30V and maintains a quiescent current of typically 1.1mA, dropping below 1µA in shutdown mode. It features precision current limit with foldback, thermal limit with hysteresis, and reverse output protection. The regulator is stable with ceramic capacitors as small as 10µF.
