MIC5247-1.85YML

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

The MIC5247-1.85YML is a positive fixed linear voltage regulator manufactured by Microchip Technology, formerly Micrel. It provides a stable 1.85V output with a maximum current capacity of 150mA. The device operates from an input voltage range up to 6V and features a low dropout voltage of 0.15V at full load. Key electrical specifications include a quiescent current of 150µA and a power supply rejection ratio (PSRR) of 50dB at 1kHz. It is housed in a compact 6-DFN (2x2mm) package with an exposed pad for thermal dissipation.
