LESHAN RADIO COMPANY, LTD
Micropower 300mA Ultra Low-Dropout CMOS Voltage
Regulator with Power Good
LR3989
General Description
The LR3989 is a 300mA low dropout
regulator designed specially to meet requirements of Portable battery applications.
The LR3989 is designed to work with space saving, small 1µFceramic capacitor.
The LR3989 features an Error Flag output that indicates a faulty output condition.
The LR3989's performance is optimized for battery powered systems to deliver low noise, extremely low dropout voltage and low quiescent current.
Regulator ground current increases only slightly in dropout, further prolonging the battery life.
Power supply rejection is better than 60 dB at l...
