LP5904TME-2.8/NOPB

LP5904 www.ti.com SNVS637G – MARCH 2011 – REVISED APRIL 2013 Ultra Low Noise, 200 mA Linear Regulator for RF/Analog Circuits - Requires No Bypass Capacitor Check for Samples: LP5904 FEATURES PACKAGE • • 1 • • • • Stable with 1.0 µF Ceramic Input and Output Capacitors No Noise Bypass Capacitor Required Remote Output Capacitor Placement Thermal-overload and Short-circuit Protection –40°C to +125°C Junction Temperature Range for Operation DESCRIPTION The LP5904 is a linear regulator capable of supplying 200 mA output current. Designed to meet the requirements of RF/ Analog circuits, the LP5904 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Using new innovative design techniques the LP5904 offers class-leading device noise performance without a noise bypass capacitor and the ability for remote output capacitor placement. An active pulldown circuit with a 280Ω resistor is wired from the output to ground pins to quickly discharge output when the device is disabled (VEN = low).
