PC1093
ADJUSTABLE PRECISION SHUNT REGULATORS
DESCRIPTION
The
µ
PC1093 are adjustable precision shunt regulators with guaranteed thermal stability. The output voltage can
be set to any value between reference voltage (2.495 V) and 36 V by two external resistors.
These ICs can apply to error amplifier of switching regulators.
FEATURES
• High Accuracy
• Low Temperature Coefficient
• Adjustable Output Voltage by two External Resistors
• Low Dynamic Impedance
