FAN2502527X

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

The FAN2502527X is a fixed positive low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It utilizes CMOS technology to provide a stable 2.7 V output with a maximum load current capability of 150 mA. The device operates within an input voltage range that supports low-voltage applications and maintains regulation across a wide temperature range from -40°C to +125°C. Key electrical specifications include a line regulation of 0.3%/V and a load regulation of 2%. The unit is housed in a compact SOT-23-5 surface-mount package, weighing approximately 30 mg, designed for efficient power management in portable electronics.
