DESCRIPTION
The 42117 series of fixed voltage regulators covers the output voltage range from -5 VDC through -30 VDC. These voltage regulators are fabricated using hybrid techniques and will operate at case temperatures up to +200°C. These devices are complete with internal short circuit protection, which includes voltage shutdown and current foldback. It is strongly recommended that input and output capacitors be added as close to the case as possible. A 2µf capacitor should be added to the input and a minimum of 1.5µf capacitor should be added to the output. See typical connection diagram below. ABSOLUTE MAXIMUM RATINGS AT 200°C CASE TEMPERATURE Typical Connection Diagram Note: D1 should be installed for input safety CASE INPUT OUTPUT - COMMON - 2uf 1.5µf RECTIFIED VOUT 1 REGULATED AS REQUIRED VIN AS REQUIRED HEADER
