Additional Details

The LT1962 series are micropower, low noise, low dropout regulators. The devices are capable of supplying 300mA of output current with a dropout voltage of 270mV. Designed for use in battery-powered systems, the low 30µA quiescent current makes them an ideal choice. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators.

A key feature of the LT1962 regulators is low output noise. With the addition of an external 0.01µF bypass capacitor, output noise drops to 20µVRMS over a 10Hz to 100kHz bandwidth. The LT1962 regulators are stable with output capacitors as low as 3.3µF. Small ceramic capacitors can be used without the series resistance required by other regulators.

Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The parts come in fixed output voltages of 1.5V, 1.8V, 2.5V, 3V, 3.3V and 5V, and as an adjustable device with a 1.22V reference voltage. The LT1962 regulators are available in the 8-lead MSOP package.

Product Detail

Demonstration circuit SCP-LT1962-EVALZ is a 20V, 300mA Low Dropout (LDO) regulator designed to allow low noise operation in noise sensitive circuits. It is easily configured for a wide output range and can provide extremely quiet operation with its high PSRR.

Like all boards in the Signal Chain Power series, this board is designed to be easily plugged into other SCP boards to form a complete signal chain power system, enabling fast evaluation of low power signal chains. To evaluate this board, some universal SCP hardware is required, namely:

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

To properly evaluate SCP series demo boards, you will need the SCP Configurator companion software. SCP Configurator can help you choose the right board and topology for your design.

Note that the Demo Manual does not cover details important to the operation and configuration regarding the LT1962. Please refer to the LT1962 data sheet for a complete description of the part.

Product Detail

Demonstration circuit DC339-B is a low noise micropower voltage regulator using the 300mA output current LT1962 linear regulator in an 8-lead MSOP package. The demo board has an input voltage range from 2.3V to 20V and a jumper-selectable output votlage that can be set to 1.22V, 2.5V, 3.0V, 3.3V, 5V or a user-defined value. The LT1962's low 20µVRMS (10Hz to 100kHz bandwidth) output noise and low 30µA quiescent current make the device ideal for voltage-controlled oscillators, RF power supplies and local regulators in larger systems.
