简  介:ST2L05 VERY LOW QUIESCENT CURRENT DUAL VOLTAGE REGULATOR s s s s s s s s s s s s VO1 = 1.5, 1.8, 2.5, 2.8, 3.0, 3.3V FIXED VO2 = 1.5, 1.8, 2.5, 2.8, 3.0, 3.3V FIXED OR ADJUSTABLE FROM 1.25 TO VI - VDROP GUARANTEED OUTPUT1 CURRENT: 1A GUARANTEED OUTPUT2 CURRENT: 1A ± 2% OUTPUT TOLERANCE (AT 25°C) ± 3% OUTPUT TOLERANCE OVER TEMP. TYPICAL DROPOUT 1.1V (IO1 = IO2 = 1A) INTERNAL POWER AND THERMAL LIMIT STABLE WITH LOW ESR OUTPUT CAPACITOR OPERATING TEMPERATURE RANGE: 0°C TO 125°C VERY LOW QUIESCENT CURRENT: 7mA MAX OVER TEMP. AVAILABLE IN SPAK AND IN DFN 5x6mm PACKAGE SPAK-5L DFN DESCRIPTION Specifically designed for data storage applications, this device integrates two voltage regulators, each one able to supply 1A and it is assembled in SPAK and in a new 8-PIN surface mounting package named DFN 5x6mm at 8 pins. The first regulator block supplies 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V depending on the chosen version. The second one may be fixed to the same values or adjustable from 1.25V to VI - VDROP that could power several kind of different micro-controllers. Both outputs are current limited and over temperature protected. It is worth underlining the very good thermal performance of the packages SPAK and DFN with only 2°C/W of Thermal Resistance Junction to Case. Applications are HARD DISK, CD/DVD-ROM, CD/ DVD-R/RW, COMBO (DVD-ROM+CD-R/RW).
