ETA5055
Ultra-High PSRR, Ultra-Low Iq, 500mA LDO for RF and Analog Circuits
DESCRIPTION
ETA5055 is a low-dropout (LDO) linear voltage regulator that features ultra-high power supply rejection ratio (PSRR), ultra-low quiescent current, fast start-up, and excellent line and load transient responses. Its PSRR can be as high as 102dB at 1.2V output. Therefore, ETA5055 is an ideal power supply for noise-sensitive applications such as RF transmissions, cellphones, CMOS sensors and audios etc.
ETA5055 is available in DFN1X1-4, DFN2x2-6, SOT23-5, and CSP-4 packages.
FEATURES
Ultra-High PSRR up to 102dB Typ. 94dB at 1KHz
Ultra-Low Quiescent Current: 4.
