DA.8 MAS 2-Output LDO Voltage Regulator IC Dual Regulator: 2 15 ma Very Low Crosstalk Low Dropout: 7 mv High Ripple Rejection: 62 db Low Noise: 3 µvrms Stable with Low-ESR Output Capacitors Separate

1 DA.8 MAS 2-Output LDO Voltage Regulator IC Dual Regulator: 2 15 ma Very Low Crosstalk Low Dropout: 7 mv High Ripple Rejection: 62 db Low Noise: 3 µvrms Stable with Low-ESR Output Capacitors Separate Enable/Disable Control for Both Regulators DESCRIPTION MAS is a voltage regulator IC with two low dropout voltage regulators, which both have their own enable/disable pin allowing the regulators to be turned off or on separately by pulling the particular control to low or high. Due to the low noise level of only 3 µvrms, MAS is suitable for sensitive circuits, e.g., in portable applications. In addition to the low noise level, MAS excels in dropout voltage (7 mv typical at 5 ma) and in very good crosstalk rejection. Also its ripple rejection ability of 62 db at 1 khz exceeds that of competition. FEATURES Low Noise Functionally and Pin Compatible with LP2967and LP3986 Can Be Used w/o C BYPASS, see p. 9 Auto-discharge Function Internal Thermal Shutdown Short Circuit Protection Small QFN 3x3 or Package Several Output Voltage Options Available, see Ordering Information p. 18 A wide range of values of Equivalent Series Resistance (ESR) of output capacitors can be used with MAS. This ESR range from a few mω up to a couple of Ohms combined with no minimum output current requirement makes the usage of MAS easier and low in cost. In order to save power the device goes into sleep mode when both regulators are disabled. An internal thermal protection circuit prevents the device from overheating. Also the maximum output current is internally limited.

For maximum output voltage accuracy DC leakage current through capacitor should be kept as low as possible. In any case DC leakage current must be below 1 na. Input Capacitance C IN.5 µf 1. A big enough input capacitance is needed to prevent possible impedance interactions between the supply and MAS. 2. Ceramic, tantalum, and film capacitors can be used. If a tantalum capacitor is used, it should be checked that the surge current rating is sufficient for the application. 3. In the case that the inductance between a battery and MAS is very small (<.1 µh).47 µf input capacitor is sufficient. 4. The value of C IN should not be smaller than the value of C L. Values given on the table are minimum requirements unless otherwise specified. When selecting capacitors, tolerance and temperature coefficient must be considered to make sure that the requirement is met in all potential operating conditions. 9 (19)

10 DA.8 APPLICATION INFORMATION Auto-Discharge Function MAS includes auto-discharge function, which means that a shutdown transistor turns on and discharges the output capacitor, when the particular output of MAS is turned off. Calculating Maximum Power Dissipation Maximum power dissipation of the package may limit output current or input voltage, which can be used, especially with the combination of low output voltage and high input voltage. The power dissipation can be calculated by using the formula: ( VIN VOUT )* IOUT VIN * IGND P d = + It shall not exceed the maximum power dissipation, allowed by the package: TJMAX T P A dmax = RJA where T JMAX is maximum junction temperature (T JMAX = 125 C), T A is ambient temperature and R JA is junction-to-ambient thermal resistance of the package. When assumed that: T A = +65 C, V OUT = 1.8 V, V IN = 5.3 V and used package is QFN x3 8ld the equation yields: 125 C 65 C P dmax = =.94 W 64 C/W from which can be calculated: P I dmax OUTMAX = = 268 ma VIN VOUT V IN * I GND is negligible and can be omitted. Consequently, it can be seen that under these conditions the average output current should not exceed 268 ma. 1 (19)
