DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC1093
ADJUSTABLE PRECISION SHUNT
REGULATORS
DESCRIPTION
The µPC1093 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 VREF = 2.495 V ± 2 %
∆VREF/∆T ≤ 100 ppm/°C
VREF ≤ VO ≤ 36 V | ZKA | = 0.1 ΩTYP.
