Specifications

The TCR5SB25U(TE85L) typically offers a fixed output voltage of 2.5V with a low dropout voltage, typically around 0.14V at a specified output current. The low quiescent current minimizes power consumption in standby mode. It includes overcurrent and thermal shutdown protection to prevent damage from overload or overheating. The small surface mount package is designed for efficient PCB assembly. The device is stable with ceramic output capacitors, contributing to system stability and reducing the need for bulky electrolytic capacitors. The operating temperature range is typically from -40°C to +85°C.

This LDO regulator provides a stable and efficient power solution for a wide range of applications, especially those requiring low power consumption and compact size. The integrated protection features enhance system reliability and simplify the design process.
