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