1. With the amount of detection, drive LCD screen to achieve the battery energy status display
2. Automatically identify the battery polarity
3. Built-in reference source, no-load regulator output, no external components to adjust the no-load voltage
General Description The RT9167/A is a 300mA/500mA low dropout and low noise micropower regulator suitable for portable applications. The output voltages range from 1.5V to 5V in 100mV increments and 2% accuracy. The RT9167/A is designed for use with very low ESR capacitors. The output remains stable even with 1μF ceramic output capacitor.
The RT9167/A uses an internal P-MOSFET as the pass device, which does not cause extra GND current in heavy load and dropout conditions. The shutdown mode of nearly zero operation current makes the IC suitable for battery powered devices. Other features include a reference bypass pin toimprove low noise performance, current limiting, and over temperature protection.
