Adjustable voltage regulator

The CHT-VEGA is single chip, positive, adjustable linear voltage regulator with low drop-out. The output voltage can be adjusted by means of an external 2-resistor bridge. The CHT-VEGA is available in a tiny ceramic package TDFP-16 for applications where small PCB footprint is critical.

Typical performances:

  • Temperature range: -55°C to 225°C
  • Input Voltage: 4.5V  to 5.5V
  • Output voltage: 1.2V to 3.3V (adjustable)
  • Maximum Output current: 500mA
  • Total precision (absolute + drift): +/-5%
  • Over-current limitation
  • Thermal protection: 300°C Typ.
  • Quiescent current: 1mA
  • Available packaging: TDFP16 



Regulated power supply in down-hole, aerospace and industrial systems.
