ST1L04PT

ST1L04 Low quiescent current voltage regulator Datasheet - production data Description PPAK Features • Adjustable output voltage from 0.8 V to VI -VD • Internal reference voltage • Accuracy ± 2% at 25 °C 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. • Output current capability: 1 A minimum • Very low quiescent current: max. 3 mA over the whole temperature range • Maximum dropout 1 V @ IO = 1 A • Stable with low ESR ceramic capacitors only • Thermal shutdown protection with hysteresis Order code Package • Overcurrent protection ST1L04PT PPAK • Operating junction temperature range: from 0 to 125 °C Table 1.

Pin connection (top view) Table 2. Pin description Pin Name Function 1 VI Supply voltage input pin. Bypass with a ceramic capacitor to GND 2 N.C. Not connected 3 GND Ground. The exposed metallic pad of the package is connected to GND 4 ADJ Adjust voltage pin. External resistor divider connection 5 VO Output voltage pin. Bypass with a ceramic capacitor to GND Figure 3. Typical application schematic The adjustable output voltage is set by a resistor divider connected between VO and GND with its centre tap connected to ADJ. The voltage divider resistors are: R1 connected between VO and ADJ and R2 connected between ADJ and GND. VO is given by VREF, R1, R2, IADJ, as follows: VO=VREF(1+R1/R2)+IADJR1 since IADJ is very small and stable, it can be ignored and the output voltage can be simply calculated as follows: VO=VREF(1+R1/R2) DocID11194 Rev 2 3/17 17 Maximum ratings 2 ST1L04 Maximum ratings Table 3.
