The LP5977-Q1 is a low noise LDO capable of delivering 250 mA output current. Designed specifically to meet RF and analog circuit requirements, the LP5977-Q1 features low noise, high PSRR, low static current, and low line or load transient response graphs. Using new and innovative design technology
Typical application
The LP5977-Q1 provides best-in-class noise performance without the ability to place noise bypass capacitors and remote output capacitors. The device is designed for use with 1-µF input and 1-µF output ceramic capacitors (separate noise bypass capacitors are not required). The device has a fixed output voltage from 1.2V to 4.5V in 25 mv steps.
