The LP5907MFX-4.5/NOPB is a single channel low dropout (LDO) linear regulator with fixed output for RF and analogue circuits in 5 pin SOT-23 package. This regulator provides ultra low noise, high PSRR, low quiescent current and low line or load transient response. Using new innovative design techniques, the LP5907 offers class leading noise performance without noise bypass capacitor and ability for remote output capacitor placement. The device is designed to work with 1μF input and 1μF output ceramic capacitor (no separate noise bypass capacitor is required). The single 1μF ceramic output capacitor can be placed up to 10cm away from the LP5907 device.
- Fixed output voltage of 4.5V
- Input voltage range from 2.2V to 5.5V
