- The AT5250/AT5250A series voltage regulators are specifically designed for use as a power source for video instruments, handheld communication equipment, and battery powered equipment. The AT5250/AT5250A series voltage regulator ICs feature a high accuracy output voltage and low GND current.
600mA Ultra Low Dropout Regulator--AT805
一 概述
The AT805 is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at 600mA amps. It operates with a VIN as low as 1.8V, with output voltage programmable as low as 0.8V. The AT805 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the AT805 has an enable pin to further reduce power dissipation while shut down. The enable pin may be tied to VIN if it is not required for ON/OFF control. The AT805 provides excellent regulation over variations in line, load and temperature.
二 特性
Typically 250mV Dropout @600mA Input Voltage Range: 1.8V to 5.5V Enable Function Over Current and Over Temperature Protection 5µA Quiescent Current in Shutdown P-CH Design to Reduce the Operation Current Adjustable Output Voltage Range 0.8V to 5V Output Voltage Accuracy ±2% Supply Current Typically 0.4mA Built-In Over Shoot Protection Circuit Ultra Fast Transient Response.
