LINEAR LT3023 Data Sheet
Summary
This dual micropower regulator is engineered for high-efficiency, low-noise power management in battery-powered portable electronics. Featuring 100mA per channel and ultra-low quiescent current (<0.1mA), it ensures stable, clean voltage output across a wide input range (1.8V to 20V). The accompanying manual details critical electrical characteristics, robust protection features (including reverse battery defense), and application guidelines, making the LT3023 the ideal solution for designers creating cellular phones, pagers, and advanced frequency synthesizers.

LT3023 Dual 100m A,
Low Dropout, Low Noise, Micropower Regulator
FEATURES DESCRIPTIO Low Noise: 20µVRMS (10Hz to 100k Hz) The LT®3023 is a dual, micropower, low noise, low drop- Low Quiescent Current: 20µA/Channel out regulator. With an external 0.01µF bypass capacitor, Wide Input Voltage Range: 1.8V to 20V output noise drops to 20µVRMS over a 10Hz to 100k Hz Output Current: 100m A/Channel bandwidth. Designed for use in battery-powered systems, Very Low Shutdown Current: <0.1µA the low 20µA quiescent current per channel makes it an Low Dropout Voltage: 300m V at 100m A ideal choice. In shutdown, quiescent current drops to less Adjustable Output from 1.22V to 20V than 0.1µA. Shutdown control is independent for each Stable with 1µF Output Capacitor channel, allowing for flexibility in power management. The Stable with Aluminum, Tantalum or device is capable of operating over an input voltage from Ceramic Capacitors 1.8V to 20V, and can supply 100m A of output current from Reverse Battery Protected each channel with a dropout voltage of 300m V. Quiescent No Reverse Current current is well controlled in dropout. No Protection Diodes Needed
