RS7206
300mA CMOS LDO Linear Regulator with Enable
概述
The RS7206 is a 4‐Low (Low‐dropout, Low‐quiescent Current, Low‐noise, Low‐cost) linear regulator with ON/OFF control.
The device operates in the input voltage range from +2.2V to +7.0V and delivers 300mA output current.
The high‐accuracy output voltage is preset at an internally trimmed voltage 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V or 3.3V. Other
output voltages can be mask‐optioned from 1.2V to 5.0V with 100mV increment.
The RS7206 consists of a 1.0V reference compare amplifier, a P‐channel pass transistor, and an enable/disable logic circuit.
其它特点包括短路保护和热关断保护。
该RS7206还具有低ESR的陶瓷电容,使输出增加稳定性兼容。这种稳定性可
由于芯片的优异的瞬态响应时的负载变动,即使保持。该RS7206设备
