特性和优点

  • Input Voltage Range: -2.7V to -20V
  • Resistor Programmed -15V Output Voltage
  • Maximum Output Current: -200mA
  • The configuration jumper selects between connecting the EN pin to the VIN pin to turn the regulator ON, or using an external EN signal to turn the regulator ON
  • Jumper connects the SENSE/ADJ Pin to the Output through a resistor divider or directly
  • VIN, VOUT, and GND test points for Regulation and Dropout Voltage Monitoring
  • 6-Lead (2mm x 2mm) LFCSP Package or 5-Lead TSOT Package

产品详情

The ADPL42092 evaluation boards evaluate the ADPL42092, a -20V, -200mA, low-noise, low-dropout linear regulator, in two packages: 6-Lead Lead Frame Chip Scale Package (LFCSP) and 5-Lead Thin Small Outline Transistor (TSOT). The circuits designed with the ADPL42092 are used primarily in noise-sensitive applications, communications and infrastructure, medical and healthcare, and industrial and instrumentation.
