Technical content
35V/2.6 µA/200mA ，Ultra-Low-Iq, Low Dropout LDO Descriptions EC85XX series is designed for power-sensitive applications. It includes a precision and high voltage input stage, an ultra- low-power bias current branch, and results in a ultra-low-power and low-dropout linear regulator. The EC85XX operates from an input voltage of VOUT +1V to 35V, consumes only 2.6 µA of quiescent current, and offers 2% initial accuracy and low dropout voltage, 300mV typical at 100mA. circuit protection and thermal shutdown. Feature ■ Ultra Low Quiescent Current: 2.6 µA(Typ.) ■ Wide Operating Voltage: V OUT +1V to 35V ■ High output current: ≥200mA ■ System startup with no overshoot ■ Short circuit protection is designed with no overshoot ■ Low Dropout Voltage ■ High Accuracy Output Voltage: ±2% ■ Excellent power / load transient response ■ Low temperature coefficient: ±100ppm/ к ■ Thermal and Short-Circuit Protection ■ SOT-89 and SOT-23 package ■ Customer Pin Assignments are available Application ■ Battery-powered Smoke sensor ■ Smoke sensor ■ Microcontrollers ■ Household appliances and instruments
