DESCRIPTION
The ST1L04 is a low drop adjustable linear
voltage regulator capable to supply up to 1A
output current.
The output voltage can be as low as 0.8V. The
quiescent
current
is
maintained below 3mA over the whole allowed
well
controlled
and
junction temperature range. The ST1L04 is stable
only with low ESR output ceramic capacitors.
Internal protection circuitry includes thermal
protection with hysteresis and over current
limiting.
The ST1L04 is especially suitable for applications
requiring low voltage outputs from low voltage
inputs. Typical application for this product are,
notebook PCs, low voltage ASIC, VID power
supplies and low cost post regulation for 3.3V
output voltage switching regulators.
