LT3032IDE#PBF General Description

The LT3032 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.

Key Features

Low Quiescent Current: 30μA/Channel
Wide Input Voltage Range: ±2.3V to ±20V
Output Current: ±150mA
Low Shutdown Current: <3μA Total (Typical)
Low Dropout Voltage: 300mV/Channel
Fixed Output Voltages: ±3.3V, ±5V, ±12V, ±15V
Adjustable Outputs from ±1.22V to ±20V
No Protection Diodes Needed
Stable with 2.2μF Output Capacitors
Stable with Ceramic, Tantalum or Aluminum Capacitors
Starts into Reverse Output Voltage
Current Limit and Thermal Limit
Low Profile 14-Lead 4mm × 3mm × 0.75mm DFN Package

Application

Battery-Powered Instruments
Bipolar Power Supplies
Low Noise Power Supplies
