1 / 13 page Rev F: Nov 2-06 SPX43A,B,C Precision Adjustable Shunt Regulator © 2006 Sipex Corporation Precision Adjustable Shunt Regulator The SPX43 is a three-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference. The SPX431 acts as an open-loop error amplifier with a 2.5V temperature compensation reference. The SPX431 has thermal stability, wide operating current of 150mA and broad temperature range of 0°C to 150°C, making it suitable for a variety of applications which require a low-cost, high performance solution. SPX431A tolerance of 0.5% is proven to be sufficient to overcome all other errors in the system to virtually eliminate the need for trimming in the power supply manufacturer's assembly line and contribute a significant cost savings. The output voltage may be adjusted to any value between VREF and 36 volts with two external resistors. The SPX431 is available in SOIC-8, SOT-23-3, SOT-23-5, SOT89, and TO-92 packages. SPX431A,B,C FEATURES • Trimmed Bandgap: 0.5%, 1% and 2% • Wide Operating Current: 1mA to 150mA • Extended Temperature Range: 0°C to 105°C • Low Temperature Coefficient: 30 ppm/°C • Improved Replacement in Performance for TL43 • Low Cost Solution • Available in Lead Free, RoHS compliant packaging: SOIC, SOT-89, SOT-23-3, SOT-23-5, and TO-92 APPLICATIONS • Battery Operated Equipment • Adjustable Supplies • Switching Power Supplies • Error Amplifiers • Single Supply Amplifier • Monitors/VCRs/TVs • Personal Computers DESCRIPTION Anode (A) Cathode (K) 2.5V Reference (R) + - TyPICAL APPLICATIONS CIRCUIT |
