LT3032 Series - Dual 150mA Positive/Negative Low Noise …

1 LT3032 Series Dual 150mA . Positive/Negative Low Noise Low Dropout Linear Regulator FEATURES DESCRIPTION. n Low Noise : 20 VRMS ( positive ) and The LT 3032 is a dual, low Noise , positive and negative low 30 VRMS ( negative ) dropout voltage linear regulator. Each regulator delivers n Low Quiescent Current: 30 A/Channel up to 150mA with a typical 300mV dropout voltage. Each n Wide Input Voltage Range: to 20V regulator's quiescent current is low (30 A operating and n Output Current: 150mA <3 A in shutdown) and well-controlled in dropout, making n Low Shutdown Current: <3 A Total (Typical) it an excellent choice for battery-powered circuits. n Low Dropout Voltage: 300mV/Channel n Fixed Output Voltages: , 5V, 12V, 15V. Another key feature of the LT3032 is low output Noise . n Adjustable Outputs from to 20V. Adding an external 10nF bypass capacitor to each regulator n No Protection Diodes Needed reduces output Noise to 20 VRMS/30 VRMS over a 10Hz to n Stable with F Output Capacitors 100kHz bandwidth.

2 The LT3032 is stable with minimum n Stable with Ceramic, Tantalum or Aluminum Capacitors output capacitors of F. The regulators do not require n Starts into Reverse Output Voltage the addition of ESR as is common with other regulators. n Current Limit and Thermal Limit The regulators are offered as adjustable output devices with n Low Profile 14-Lead 4mm 3mm an output voltage down to the reference voltage or DFN Package in fixed voltages of , 5V, 12V and 15V. Internal protection circuitry includes reverse-output protection, current limiting and thermal limiting. APPLICATIONS. The LT3032 is available in a unique low profile 14-lead n Battery-Powered Instruments 4mm 3mm DFN package with exposed back . n Bipolar Power Supplies side pads for each regulator, allowing optimum thermal n Low Noise Power Supplies performance.
