UPC1093

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.
