MIC5255-2.6BD5

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

The MIC5255-2.6BD5 is a fixed positive low-dropout (LDO) linear voltage regulator manufactured by Micrel, now part of Microchip Technology. It provides a stable 2.6V output with a maximum continuous current capability of 150 mA. The device operates within an input voltage range of 2.7 V to 6.0 V and features an ultra-low dropout voltage of typically 135 mV at full load. It incorporates a noise bypass pin for enhanced performance in sensitive applications. The regulator is housed in a thin SOT-23-5 package with a height of 1 mm, suitable for space-constrained designs.
