It delivers up to 200 mA at an adjustable output down to -1.31 V or a fixed -15 V, switching at 50 kHz. This is a through-hole part in an 8-pin DIP package, intended for low-power bipolar rails in bench or industrial equipment running at commercial temperatures (0°C to 70°C). ## Sourcing and lifecycle No second source or direct replacement is listed by the manufacturer, but the adjustable output range covers many negative-rail needs without a custom magnetics design.","metaTitle":"MAX637ACPA+ Buck Regulator, -15 V Output, 200 mA, 8-DIP","metaDescription":"MAX637ACPA+ step-down/inverting buck regulator from Analog Devices.
