ST1L04 LOW QUIESCENT CURRENT VOLTAGE REGULATOR

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 well controlled and maintained below 3mA over the whole allowed 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
