Introduction

AI Translation

The ±Γ⊙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 adjustable output devices with an output voltage down to the ±1.22V reference voltage or in fixed voltages of ±3.3V, ±5V, ±12V and ±15V. Internal protection circuitry includes reverse-output protection, current limiting and thermal limiting.

The LT3032 is available in a unique low profile 14-lead 4mm × 3mm × 0.75mm DFN package with exposed back­ side pads for each regulator, allowing optimum thermal performance.
