Adjustable Precision Shunt Regulators
Jump to Page Section:
Overview
Description
The μPC1943, 1944 are adjustable high precision shunt regulators. The output voltage can be set to any value between reference voltage (1. 26 V) and 24 V by two external resistors. These ICs can apply to error amplifier of switching regulators.
Features
- Low voltage operation.: VREF ≤ VOUT ≤ 24 V
- High accuracy.: VREF = 1.26 V ± 2.4%
- Adjustable output voltage by two external resistors.
- Pin compatible with μPC1093. (μPC1944)
