ST2L05R3300PS

ST2L05-3300 Very low quiescent current dual voltage regulator Datasheet - production data Description Specifically designed for data storage applications, this device integrates two voltage regulators, each capable of supplying 1 A of current. It is assembled in an 8-pin DFN8 5x6 mm surface mounting package. One regulator block supplies 3.3 V and, on request, 1.5 V, 1.8 V, 2.5 V, 2.8 V and 3.0 V. The other is adjustable from 1.25 V to VI - VDROP, which is suitable for powering several different types of microcontroller. Both outputs are current-limited and overtemperature protected. Also noteworthy is the very good thermal performance of the DFN package, with only 2 °C/W of thermal resistance junction-tocase.

It is recommended to solder both capacitors as close as possible to the relative pins (1, 4 and 5). 6.2 Input capacitor An input capacitor with a value of at least 2.2 µF is required. The amount of input capacitance can be increased without limit if a good quality tantalum or aluminium capacitor is used. SMD X7R or Y5V ceramic multilayer capacitors may not ensure stability in any condition due to the variability of their frequency and temperature characteristics. The use of this capacitor type is strictly related to the use of the output capacitors. For additional details, please read the Output capacitor section below. The input capacitor must be located at a distance of not more than 0.5" from the input pin of the device and returned to a clean analog ground. 6.3 Output capacitor The ST2L05-3300 is designed specifically to work with ceramic and tantalum capacitors. Special care must be taken when a ceramic multilayer capacitor is used. Due to their characteristics, this type of capacitor can sometimes have an ESR value lower than the minimum required by the ST2L05-3300, and their relatively large capacitance can vary greatly depending on the ambient temperature. The test results for the stability of the ST2L05-3300 using multilayer ceramic capacitors show that a minimum value of 2.2 µF is needed for both regulators. This value can be increased without limit if the input capacitor value is greater than or equal to 4.7 µF, and up to 10 µF if the input capacitor is less than 4.7 µF. Surface-mountable solid tantalum capacitors offer a good combination of small physical size, capacitance value and ESR in the range needed for the ST2L05-3300. Test results show good stability for both outputs with values of at least 1 µF. The value can be increased without limit for even better performance in areas such as transient response and noise. Important: The output capacitor must maintain an ESR in the stable region over the full operating temperature to assure stability. Moreover, capacitor tolerance and variations due to temperature must be considered to assure that the minimum amount of capacitance is provided at all times. For this reason, when a ceramic multilayer capacitor is used, the better choice for temperature coefficient is the X7R type, which holds the capacitance within ± 15%. The output capacitor should be located not more than 0.5" from the output pins of the device and returned to a clean analog ground. 6.4 Adjustable regulator The ST2L05-3300 has a 1.25 V reference voltage between the output and the adjust pin (pins 4 and 2, respectively). When resistor R1 is placed between these two terminals, a constant current flows through R1 and down to R2 to set the overall (VO2 to GND) output voltage. Minimum load current is 2 mA max in all temperature conditions. DocID9506 Rev 8 15/28 28 Application hints ST2L05-3300 Figure 4.
