LX8213-00ISE中文资料Positive LDOs数据手册Microchip规格书

描述 Description

The LX8213 operates over a wide input voltage range of 2.5V to 6V, and delivers up to 300mA of output current consuming only 60uA typical quiescent current at no load and a low 0.1uA shutdown current. Output voltage options include fixed 1.2V, 2.5V, 3.3V, 5.0V or an adjustable output voltage which may be set from 800mV to 5.5V. At 300mA load, dropout voltage measures only 170mV for a 3.3V output. Tight load and line regulation is achieved over the full output current and supply range. The high bandwidth control loop provides fast transient response to reduce output voltage deviation using low cost external ceramic capacitors in the 1uF range. The LX8213 also exhibits low output noise with only 60uVRMS over a 100kHz bandwidth. Power supply rejection exceeds 65dB at 100Hz. Other features of LX8213 include an active low shutdown input with a 3M? internal pull-down for low cost power sequencing, internal soft-start circuitry to prevent inrush current, short circuit current limit, and thermal overload protection. The LDO features a foldback current limit of approximately 400mA. The LX8213 operates over -40°C to +85°C ambient temperature range.  ROHS, PB Free-->  ROHS
