DESCRIPTION
The LT®3032 is a dual, low noise, positive and negative low dropout voltage linear
regulator. Each
regulator delivers up to 150mA with a typical 300mV dropout voltage. Each
regulator’s quiescent current is low (30µA operating and <3µA in shutdown) and well-controlled in dropout, making it an excellent choice for battery-powered circuits. Another key feature of the LT3032 is low output noise. Adding an external 10nF bypass capacitor to each
regulator reduces output noise to 20µVRMS/30µVRMS over a 10Hz to 100kHz bandwidth. The LT3032 is stable with minimum output capacitors of 2.2µF. The
regulators do not require the addition of ESR as is common with other
regulators. The
regulators are offered as ...
