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 E Z 1 5 8 5 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance a t rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device.
4.6 Amp Positive Voltage Regulator
Features
u Low dropout voltage: 1.3V max. for EZ1585C and u Full current rating over line and temperature u Fast transient response u ±2% total output regulation over line, load and
temperature Adjust pin current max 90µA 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 1.4V max. for EZ1585I
u u u u A variety of options are available for maximum flexibility: u the EZ1585C is intended for commercial applications and u
h a s 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.
