LP5912Q3.3DRVRQ1 Descrizione generale

The LP5912-Q1 is low-noise LDO that can supply up to 500 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5912-Q1 device provides low noise, high PSRR, low quiescent current, and low line and load transient response. The LP5912-Q1 offers class-leading noise performance without a noise bypass capacitor and with the ability for remote output capacitance placement.

The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (no separate noise bypass capacitor required).

This device is available with fixed output voltages from 0.8 V to 5.5 V in 25-mV steps. Contact Texas Instruments Sales for specific voltage option needs.

For all available packages, see the Package Option Addendum (POA) at the end of this data sheet.
