Low Voltage Bias Stabilizer
with Enable
• Maintains Stable Bias Current in N−Type Discrete Bipolar Junction
and Field Effect Transistors
• Provides Stable Bias Using a Single Component Without Use of
Emitter Ballast and Bypass Components
• Operates Over a Wide Range of Supply Voltages Down to 1.8 Vdc • Reduces Bias Current Variation Due to Temperature and
Unit−to−Unit Parametric Changes
• Consumes t 0.5 mW at VCC = 2.75 V • Active High Enable is CMOS Compatible
This device provides a reference voltage and acts as a DC feedback element around an external discrete, NPN BJT or N−Channel FET. It allows the external transistor to have its emitter/source directly grounded and still operate with a stable collector/drain DC current.
