评估套件

eval board
DC367B

Evaluating the LT1963A, 1.5A, Low Noise, Fast Transient Response LDO Regulators

特性和优点

  • Evaluates the LT1963A in an 8-Lead SO Package
  • Maximum Output Current: 1.5A
  • Jumper Programs Output Voltage Aaccording to the Resistors Set for the Output Voltage Options: 1.21V, 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5V
  • Jumper Turns the Regulator On by Connecting the SHDN Pin to the INPUT Pin or by Connecting the Pin to an External Supply to Turn the Regulator On or Off
  • VIN, VOUT, and GND Test Points for Regulation and Dropout Voltage Monitoring
  • Component Placeholder for a Resistor Connected to JP2, Which can Modify the Required Output Voltage When the SENSE/ADJ Pin is Connected to the Output Through a Resistor Divider

产品详情

The DC367B evaluation board evaluates the LT1963A, a 1.5A low dropout (LDO), linear regulator that is optimized for fast transient response. Circuits designed with the LT1963A are used primarily in cellular phones, voltage-controlled oscillators, RF power supplies, and in larger systems as local regulators. The ability to tolerate a wide variety of output capacitors makes the LT1963A ideal for space- and cost-sensitive systems.
