The is a Dual 150mA Positive/Negative Very Low Dropout Linear Regulator featuring low noise. 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 20/30µVRMS over a 10Hz to 100kHz bandwidth. The LT3032 is stable with minimum output capacitors of 2.2µF. The regulator does not require the addition of ESR as is common with other regulators. The regulator is offered as adjustable output devices with an output voltage down to the ±1.22V reference voltage or in fixed voltages of ±3.3, ±5, ±12 and ±15V. Internal protection circuitry includes reverse-output protection, current limiting and thermal limiting.
