The IP137A series is a 1.5 amp negative adjustable voltage regulator with an output voltage range of 1.25 to 40V. The series features a 1% output voltage tolerance, 0.3% load regulation and 0.01%/V line regulation. The series features a complete range of protections including current limiting, thermal shutdown and SOA control.
The IP137A series from Semelab are negative adjustable voltage regulators available in standard and high‑voltage versions. They offer an output voltage range of 1.25 V to 40 V (standard) or 1.25 V to 50 V (HV) with 1 % output voltage tolerance, 0.3 % load regulation and 0.01 %/V line regulation. Built‑in protections include current limiting and thermal shutdown.
The datasheet lists detailed electrical parameters such as input‑output differential voltage, operating temperature range (‑55 °C to +150 °C), and thermal resistance for each package type. Application notes describe high‑stability regulator configurations, multiple‑tracking regulator designs, and ordering information for the various package options.
