1.5A, Negative Regulator Expands Family of CurrentReference Linear Regulators
Dawson Huang The LT3080, introduced in 2007, represented a new linear regulator architecture featuring
a current source as reference and a voltage follower for the output amplifier. This new
architecture has a number of advantages, including easy regulator paralleling for increased
output current and operation down to zero output voltage. Since the output amplifier always
operates at unity gain without a resistor-setting divider, bandwidth and absolute regulation
are constant across the output voltage range. Transient response is independent of output
voltage and regulation can be specified in millivolts rather than as a percent of output.
Table 1 summarizes the family of devices
that use this architecture. The LT3091,
the latest addition to this family, is a 1.5A
low dropout negative linear regulator
featuring adjustable current limit and
current monitor. The LT3091 is similar
to the other negative linear regulator in
Figure 1. 1.5A, negative linear
regulator with current limitation and
monitor 0.1ВµF LT3091 the family, the LT3090, but with more
than double the LT3090вЂ™s current rating.
The LT3091 is useful in high current,
negative voltage applications requiring
low noise or precision output. It features
fast transient response, high PSRR and …
