| EZ1585C & EZ1585I POWER MANAGEMENT Description The EZ1585 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at up to 4.6A. Additionally, the EZ1585 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. A variety of options are available for maximum flexibility: the EZ1585C is intended for commercial applications and has both fixed and adjustable voltage options; the EZ1585I is intended for industrial applications and is adjustable only. All devices are available in the popular TO-220 and TO-263 packages. 4.6 Amp Positive Voltage Regulator Features Low dropout voltage: 1.3V max. for EZ1585C and 1.4V max. for EZ1585I Full current rating over line and temperature Fast transient response 2% total output regulation over line, load and temperature Adjust pin current max 90A over temperature Fixed/adjustable output voltage (EZ1585C) Line regulation typically 0.015% Load regulation typically 0.05% Industrial temperature range (EZ1585I) TO-220 and TO-263 packages.

Available voltages are: 2.5V and 3.3V. Leave blank for adjustable version (1.3 to 5.7V). Contact factory for additional voltage options. (2) Where C and I denote Commercial (0C to 70C) and Industrial (-40C to 85C) ambient temperature ranges. (3) Only available in tape and reel packaging. A reel contains 800 devices. (4) Only available in tube packaging. A tube contains 50 devices. (5) This product is RoHS compliant. This pin is the negative side of the reference voltage for adjustable devices. Transient response can be improved by adding a small bypass capacitor from the adjust pin to ground. This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts, and should be connected to ground. This is the power output of the device and is electrically connected to the TAB. This is the input supply pin for both the control circuitry and the pass device.
