DESCRIPTION
The EZ1086 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated current.
Additionally, the EZ1086 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 EZ1086C has both fixed and adjustable
voltage options and is designed for use in commercial
applications; the EZ1086BC is adjustable only for cost
sensitive commercial applications; the EZ1086I is
adjustable only for industrial applications. All devices
are available in the popular TO-220 and TO-263
packages.
APPLICATIONS
= Post regulators
= Battery chargers
TYPICAL APPLICATIONS
FEATURES
= Low dropout voltage: 1.3V max. for EZ1086C,
1.4V max. for EZ1086I, 1.45V max. for EZ1086BC
= Full current rating over line and temperature
= Fast transient response
= ±2% total output regulation over line, load and
temperature (±2.4% for EZ1086BC)
= Adjust pin current max 90µA over temperature
= Fixed/adjustable output voltage (EZ1086C)
= Line regulation typically 0.015%
= Load regulation typically 0.05%
= Industrial temperature range (EZ1086I)
= TO-220 and TO-263 packages
